I wonder if it is possible to refresh a div tag in javascript?
My ajax script
<script type="text/javascript">
function actualiserDLIS()
{
var url = 'administration/gestionUtilisateurs.do?method=actualisationDLIs';
var params = 'DR='+encodeURIComponent(document.getElementById('selectDR').value);
var myAjax = new Ajax.Request(
url,
{ method: 'post',
parameters: params,
onComplete: majDLIS
});
}
function majDLIS(retour)
{
if (retour.status == 200)
{
document.getElementById('tableDLI').outerHTML = retour.responseText;
}else
{
document.getElementById('tableDLI').innerHTML = "uncool";
}
}
</script>
My html body
<h2 class="surlignageHaut">Restriction d'accés aux données</h2>
<label for="selectDR" >DR de l'utilisateur</label>
<html:select property="utilisateur.DR" size="1" styleId="selectDR" styleClass="saisie" style="position:relative;top:2px;left:5px;" onchange="actualiserDLIS();">
<html:optionsCollection property="optionsDRS" label="libelle" value="code"/>
</html:select>
<br/>
<br/>
<div id="tableDLI">
</div>
</div
when i select a data in my list, i do my ajax request and i have a table, when I reselect a different value in my list, my table does not update
for sure! by using ajax you can load content into your DIV-tags, as well as into many other DOM-Elements live.
Use the name of function which you describe inside the div.
Function to call the method:
window.setTimeout("name_of_the_function_present_in_div()",30000);
Here 30000 show 30 seconds, now you can modify the contents according to you requirement.

Hi I'm learning AngularJS and I have a question. I want to display a table on a button click. On clicking the button, JSON data gets fetched but I have to press the button twice for the data to be displayed.
This is the HTML page.
<html>
<body>
<div class="container">
<label for="tags" style="margin-top: 30px;margin-left: 15px;">GSTIN </label>
<input id="tags">
<button ng-click="searchfunction()">search</button>
</div>
<br/>
<hr>
<div class="container">
<div ng-show="tshow" ng-repeat="x in searchdata">
<table class="table table-bordered table-responsive">
<thead>
<tr>
<th>MON</th>
<th>SGST</th>
<th>CGST</th>
<th>IGST</th>
<th>CESS</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="i in x">
<td>{{i.mon}}</td>
<td>{{i.sgst}}</td>
<td>{{i.cgst}}</td>
<td>{{i.igst}}</td>
<td>{{i.cess}}</td>
</tr>
</tbody>
</table>
</div>
</div>
</body>
</html>
This is the controller:
app.controller("searchcontroller", function ($scope,$http) {
$scope.tshow=false;
function make_base_auth(user, password) {
var tok = user + ':' + password;
var hash = btoa(tok);
return "Basic " + hash;
}
$scope.searchfunction=function() {
$scope.tshow=true;
var tf=document.getElementById("tags");
var value=tf.value;
var auth = make_base_auth("gstadmn112","Gstn#123");
var url6 = "http://164.100.148.67:8080/wsgstr3B/rest/payment/gstinsearch?gstin="+value+"&year=201718";
xml = new XMLHttpRequest();
// jQuery
$.ajax({
url : url6,
method : 'GET',
beforeSend : function(req) {
req.setRequestHeader('Authorization', auth);
},
success:function(response) {
console.log(response);
scope.searchdata=response;
},
failure:function() {
window.alert("wrong input data doesn't exist");
}
});
}
});
I need to click twice on the search button for the table to be displayed. I want the table to be hidden initially and once the search is successful the table should be displayed. The table is hidden initially and after clicking twice correct data gets displayed.
Maybe, you try to add $scope.tshow=true; in function success:
success:function(response) {
console.log(response);
$scope.tshow=true;
$scope.searchdata=response;
},
P.S. I advise to use $http instead of $ajax.
This problem is related to the digest loop of angularjs which keeps all changes sync between your view and controller.
When you invoke the searchfunction(), angularjs will know whats happening inside the method and sync the changes made with the view when its completed.
The problem is that your method uses $.ajax which has some async callback methods.
When these methods gets invoked angularjs have already left the party (digest loops is over) and don't know what these methods have done to your controller $scope.
The jQuery success callback will however set the $scope.searchdata=response; and this change gets notified the next time angularjs is in the party (the next time you click).
So basically you need to make sure angularjs is aware of the async methods which makes changes to your $scope.
To solve this I would inject angularjs own $http service (which takes care of async changes to the scope) and use that instead.
var req = {
method: 'GET',
url: url6,
headers: {
'Authorization': auth
}
}
$http(req).then(function(response){
console.log(response);
$scope.searchdata=response;
}, function(){
window.alert("wrong input data doesn't exist");
});
You can use this way.
$scope.searchfunction=function(){
$scope.tshow=true;
var tf=document.getElementById("tags");
var value=tf.value;
$http.get("http://164.100.148.67:8080/wsgstr3B/rest/payment/gstinsearch?gstin="+value+"&year=201718")
.success(function(result) {
$scope.searchdata=response;
$scope.tshow=false;
})
.error(function() {
window.alert("wrong input data doesn't exist");
});
}
I've been getting crazier day after day with this, I can't find an answer, I've spent like 100h+ with this... I hope someone could help me out!
UPDATE:
So to make myself more clear on this issue and be able to get help from others, I basically have 3 containers named "main-container" they all have 3 containers as childs all with the same class name, and when I submit the button, I trigger an ajax function to load the JSON strings comming from php into the child divs, the problem is that I get the 3 "main_containers" to load the ajax at the same time, I only want to load the ajax if I press the button of each "main_container" individually.
I've been using jquery and vanilla JS as well but seems I just can't get it done!
This is how I currently trigger the button with jquery:
$('.trigger_button_inside_divs').click(my_ajax_function);
And this is how my ajax looks like:
function my_ajax_function(){
$.ajax({
dataType: "JSON",
type: 'POST',
url: test.php,
success: function(data) {
$('.div_to_render_JSON_1').html(data.PHP_JSON_1_RECEIVED);
$('.div_to_render_JSON_2').html(data.PHP_JSON_2_RECEIVED);
$('.div_to_render_JSON_3').html(data.PHP_JSON_3_RECEIVED);
}
});
}
HTML looks like this:
<div class="main_container">
<div class="my_div">
//div_to_render_JSON_1
</div>
<div class="my_div">
//div_to_render_JSON_2
</div>
<div class="my_div">
//div_to_render_JSON_3
</div>
<button class="trigger_ajax_function_btn">Click to load ajax</button> //this btn loads ajax into the div class "my_div"
</div>
<div class="main_container">
<div class="my_div">
//div_to_render_JSON_1
</div>
<div class="my_div">
//div_to_render_JSON_2
</div>
<div class="my_div">
//div_to_render_JSON_3
</div>
<button class="trigger_ajax_function_btn">Click to load ajax</button> //this btn loads ajax into the div class "my_div"
</div>
<div class="main_container">
<div class="my_div">
//div_to_render_JSON_1
</div>
<div class="my_div">
//div_to_render_JSON_2
</div>
<div class="my_div">
//div_to_render_JSON_3
</div>
<button class="trigger_ajax_function_btn">Click to load ajax</button> //this btn loads ajax into the div class "my_div"
</div>
So in conclusion, each of those 6 "divs" has a button that triggers an function containing my ajax to render inside that particular div. But what I get is that every time I click that triggering button, I get the ajax to render in all of the 6 divs, instead of render on each particular div only when I click its particular button.
Thanks a lot people, I really hope to get this done!
Cheers.
PD:
This is something a programmer did to achieve what I'm trying to achieve but I just can't figure out what in this code is that is making possible clicking 1 button and affect THAT html element , even though they all have the same class.
(function(){
$("form input[type=submit]").click(function() {
$("input[type=submit]", $(this).parents("form")).removeAttr("clicked");
$(this).attr("clicked", "true");
});
var xhr = new XMLHttpRequest();
var el;
function SetDataInTheForm()
{
var resp = JSON.parse(xhr.response)
var pt=0
var ct=0
var gt=0
Array.prototype.forEach.call(el.querySelectorAll(".test"),function(e,i){
e.innerHTML=resp[i].name
})
Array.prototype.forEach.call(el.querySelectorAll(".p"),function(e,i){
e.innerHTML=parseFloat(resp[i].p).toFixed(0)
pt+=parseFloat(resp[i].p)
})
Array.prototype.forEach.call(el.querySelectorAll(".c"),function(e,i){
e.innerHTML=parseFloat(resp[i].c).toFixed(0)
ct+=parseFloat(resp[i].c)
})
Array.prototype.forEach.call(el.querySelectorAll(".g"),function(e,i){
e.innerHTML=parseFloat(resp[i].g).toFixed(0)
gt+=parseFloat(resp[i].g)
})
el.querySelector(".wtp").innerHTML=parseFloat(resp[0].total).toFixed(0)+" "+resp[0].unit
el.querySelector(".wtc").innerHTML=parseFloat(resp[1].total).toFixed(0)+" "+resp[1].unit
el.querySelector(".wtg").innerHTML=parseFloat(resp[2].total).toFixed(0)+" "+resp[2].unit
el.querySelector(".pt").innerHTML=pt.toFixed(0)
el.querySelector(".ct").innerHTML=ct.toFixed(0)
el.querySelector(".gt").innerHTML=gt.toFixed(0)
}
function HandleSubmit(e)
{
el=e.currentTarget
e.preventDefault();
xhr.open("POST","/url_here.php",true)
xhr.setRequestHeader("content-type","application/x-www-form-urlencoded")
xhr.onload=SetDataInTheForm
var button=e.currentTarget.querySelector("input[type=submit][clicked=true]")
button.removeAttribute("clicked")
xhr.send($("#"+e.currentTarget.id).serialize()+"&"+button.getAttribute("name")+"=on")
}
[].forEach.call(document.querySelectorAll("._form_"),function(form){
form.addEventListener("submit",HandleSubmit,false);
})
})()
Remember that $('.div_container_to_render_JSON') is a new selector that selects all elements with a class div_container_to_render_JSON. What you want to happen is figuring out where that click came from, and find the corresponding div_container_to_render_JSON.
Luckily for you, a jQuery click handler sets the this keyword to the HTMLElement where the click was captured. You can use this to get the parent element.
$('.your-button').on('click', function () {
const myButton = $(this);
$.ajax({
// ...
success (data) {
myButton.parent().html(data.PHP_JSON_RECEIVED);
// or if you need to find a parent further up in the chain
// myButton.parents('.div_container_to_render_JSON').html(data.PHP_JSON_RECEIVED);
}
});
});
The problem is that your class selector is indeed selecting all your divs at the same time.
Solution, set identifiers for your divs as such:
<div class="my_div" id="my_div_1">
and then you can use those id's to fill in the data:
$('#my_div_1').html(data.PHP_JSON_1_RECEIVED);
and repeat for your 6 divs (notice the change from class selector '.' to identifier selector '#')
Thanks for the replies people. I finally figured it out after days of hard work, it was something really simple.. here's the answer:
$('.trigger_button_inside_divs').click(my_ajax_function);
var thisButton = $(this);
var thisDiv = thisButton.closest(".main_container");
function my_ajax_function(){
$.ajax({
dataType: "JSON",
type: 'POST',
url: test.php,
success: function(data) {
thisDiv.find('.div_to_render_JSON_1').html(data.PHP_JSON_1_RECEIVED);
thisDiv.find('.div_to_render_JSON_2').html(data.PHP_JSON_2_RECEIVED);
thisDiv.find('.div_to_render_JSON_3').html(data.PHP_JSON_3_RECEIVED);
}
});
}
I am currently coding within a ViewComponent (ViewComponent1) view. Within this View, I have listed a few items:
As you can see, the channels 11, 12, 13 and 14 are clickable. Each channel has some additional information (OBIS, avtalsid.. etc). What I´m trying to do is to invoke ViewComponent2, within ViewComponent1, and pass along some of the data, based on the clicked item.
What I tried to do is to create another View called "Test" and within that View invoke ViewComponent2 along with its parameters, like this:
<div class="row">
<div class="col-md-2 canalstyle">
<a asp-controller="Customer" asp-action="Test" asp-route-pod="#item.STATION"
asp-route-idnr="#item.IDNR" asp-route-kanal="#item.KANAL" asp-route-start="#Model.start"
asp-route-end="#Model.end"> #Html.DisplayFor(modelItem => item.KANAL)</a>
</div>
</div>
This works, but this method redirects me away from my current View (ViewComponent 1). I don't want that. I want the current view to load the additional information from ViewComponent2.
My function that runs the ajax:
function myFunction() {
var data = JSON.stringify({
'idnr': id,
'start': this.start,
'end': this.end
});
$.ajax({
url: '#Url.Action("Test2","Customer")',
type: 'GET',
data: { idnr: id, start: this.start, end: this.end },
contentType: 'application/json',
success: handleData(data)
})
};
function handleData(data) {
alert(data);
var url = $(this).attr("href");
var $target = $(this).closest("div").find(".details");
$.get(url, function (res) {
$target.html(res);
});
//do some stuff
}
And my Test2 Action:
public async Task<IActionResult> Test2(string idnr, string start, string end)
{
ServiceClient r2s = new R2S.ServiceClient();
R2S.Konstant[] kData = r2s.GetKonstantListAsync(new string[] { "IDNR" }, new string[] { idnr}).Result; // mätarnummer in... --> alla konstanter kopplade till denna.
return ViewComponent("MeterReader2", new { k = kData[0], start = start, end = end });
}
I am trying to target the same DOM.. Any ideas?
Your current code is rendering links (a tags) and normally clicking on a link will do a new GET request, which is what you are seeing , the redirect to the new action method.
If you do not want the redirect, but want to show the result of the second view component in same view, you should use ajax.
For example, If you want to show the result of second view component just below each link, you may add another html element for that. Here i am adding an empty div.
<div class="row">
<div class="col-md-2 canalstyle">
<a class="myClass" asp-controller="Customer" asp-action="DetailsVc"
asp-route-id="#item.Id" > #item.KANAL</a>
<div class="details"></div>
</div>
</div>
Here i just removed all those route params you had in your orignal question and replaced only with on param (id) . Assuming your items will have an Id property which is the unique id for the record(primary key) and using which you can get the entity (from a database or so) in your view component to get the details.
This will generate the link with css class myClass. You can see that, i used asp-action attribute value as "DetailsVc". We cannot directly use the view component name in the link tag helper as attribute value to generate the href value. So we should create a wrapper action method which returns your view component result such as below
public IActionResult DetailsVc(int id)
{
return ViewComponent("DetailsComponent", new { id =id });
}
Assuming your second view components name is DetailsComponent and it accepts an id param. Update the parameter list of this action method and view component as needed. (but i suggest passing just the unique Id value and get details in the server code again)
Now all you have to do is have some javascript code which listen to the click event on those a tags and prevent the normal behavior (redirect) and make an ajax call instead, use the ajax call result to update the details div next to the clicked link.
You can put this code in your main view (or in an external js file without the #section part)
#section Scripts
{
<script>
$(function() {
$("a.myClass").click(function(e) {
e.preventDefault();
var url = $(this).attr("href");
var $target = $(this).closest("div").find(".details");
$.get(url,function(res) {
$target.html(res);
});
});
});
</script>
}
i am creating form using js functions.. i want that when this function is called twice form should be created twice.. i am using jquery load hence it is overwriting again and again...
my jquery code:
function form(module,user) {
$.post("php/test.php",{ module:module , user:user}, function(data, status){
var f= jQuery.parseJSON( data );
$(".cards-container").load("modules/ams.html",function(){
$(".cards-container > div").addClass("card card-shadow animated fadeInDown");
$(".form-t").append("<input type='text'"+"placeholder="+f.text+" name='fname' required>");
});
});}
form("home",200);form("home",300);
AMS.html:
<div class='w100 large forms'>
<form action='test.php' method='post'>
<div class="form-t"></div>
<input type='submit' value='Submit'></form>
</div>
JQuery load() method always replaces content of "element-receiver". Use get() method to request new content with subsequent appending:
var f= jQuery.parseJSON( data );
$.get('modules/ams.html', function(data){
$(".cards-container").append(data);
$(".cards-container > div").addClass("card card-shadow animated fadeInDown");
$(".form-t:last").append("<input type='text'"+"placeholder="+f.text+" name='fname' required>");
});
Load will always overwrite. It is a shortcut function for an Ajax method. So instead, use Ajax so you have control of the result:
$.ajax({
url: "modules/ams.html",
type: "GET"
}).done(function (result) {
$(".cards-container").append(result);
});
This will just append the content directly into the container. You will have to apply any other logic you need. Remember that ids should be unique and forms cannot be nested so make sure you avoid loading html with a form when your container is already within a form.
I have a form in jQuery where I update all the images via a simple ajax call to reload the entire page. Unfortunately the captions are included in that form as well, and as I start writing, my captions are overwritten.
What then would you do to keep them?
Would you..
Save them before the ajax call and replace them after it?
Avoid updating the captions all together?
The latter seems like the best choice, I'm just not entirely sure how I would implement calling an AJAX call but just updating the images .
My sweet updater
$.extend({
PhotoUpdater: {
startUpdate: function(organization, gallery){
url = "/organizations/" + organization + "/media/galleries/" + gallery + "/edit_photo_captions"
timer = window.setTimeout(function(){
$.PhotoUpdater.doUpdate(url)
}, 5000)
},
stopUpdate: function(){
clearTimeout(timer);
timer = 0;
},
doUpdate: function(url){
$.ajax({type: "GET", url: url, dataType: "script"});
},
resetValues: function(){
setTimeout(function(){ $("body").data("edit_photos_closed", "false");
$.PhotoUpdater.stopUpdate();
}, 3000 );
}
}
});
my html
<div class="alpha grid_4 zebraCaption">
<img src="/tumblr_l0x861Yc5M1qbxc42o1_400.jpg" id="thumb_216" alt="Trippy Long Stockings's amazing picture">
<br>
<label for="gallery_photos_attributes_0_caption">Caption</label>
<br>
<input type="text" style="width: 236px;" size="35" name="gallery[photos_attributes][0][caption]" maxlength="35" id="gallery_photos_attributes_0_caption">
<br>
<a class="button_small facebox_window" href="/organizations/1/media/galleries/26/photos/216/edit_facebox_captions?captions_screen=true">edit crop</a>
<a id="remove_crop_216" class="button_small remove_crop_button" href="http://localhost:3000/photos/216/toggle_crop">remove crop</a>
</div>
You could try something like this:
If you have 10 images on the page then the AJAX response could be a JSON array of 10 img sources. You can then do:
var imgArray = {JSON ARRAY FROM AJAX}
$('img').each(function(index){
$(this).attr('src',imgArray[index]);
});
This would only work if you know the order of the images on the page, though, or they are identified by IDs.
