I am not so good at JS, but I am trying to add dynamically a row with content (clone). This is working, IF I put
var apcount = 0;
function add(id, apmax) {
var aptable = id;
if (apmax > apcount) {
$("table tr:last").clone().appendTo("#m1s1t2").find(':input').attr('name', function(index, name) {
return name.replace(/(\d+)$/, function(fullMatch, n) {
return Number(n) + 1;
});
})
}; apcount++;
}
the 'id' direct into '.appendTo'. The call of this function is a button
<input onclick="add('m1s1t2',2)" type="button">
Actually I want to have something like '.appendTo(id)'
Anyone an idea?
So use the id variable you pass in
change
.appendTo("#m1s1t2")
to
.appendTo("#" + id)

I have the following ForEach in my razor where i am setting some values.
It works fine. I can see my all values.
#foreach (var item in Model.ConsultantDetails.ScopeOfSevrices)
{
<div id="optionValue" class="item" data-value=>#item.Name</div>
}
Then i have an ajax call and get the result back.
I want to set this data back to same DIV by iterating
$.each(data.ConsultantDetails.ScopeOfSevrices, function (index) {
$('optionValue').attr("data-value=>", data.ConsultantDetails.ScopeOfSevrices[index].Name);
});
No luck, how do i achieve that?
use for loop instead of foreach, so we can set seprate id to each iteration
dont use data-value=> , instead use data-value=" " or some dummy value (here we use : item.Name)
#for (int i = 0; i < Model.ProductTypeService.Count; i++)
{
var item = Model.ProductTypeService[i];
var id = "optionValue" + i;
<div id="#id" class="item" data-value="#item.Name">#item.Name</div>
}
finally, in jquery, we can assign attribute value based on div id
$.each(data.ProductTypeService, function (index) {
$('#optionValue' + index).attr("data-value", data.ProductTypeService[index].Name + index); // + index // just to see different value
});
How i can filter my JSON object with array.
FIDDLE
This is an sample of my json object and code, i want to filter final render HTML by selected checkbox.
Thanks for your help
function init(arr){
var li = '';
$.each(jsn, function (key, value) {
if (arr.length == 0) {
li += '<li>' + jsn[key].name + '</li>';
}else{
$(arr).each(function (i, v) {
// this section must be filter "pack's" but i can't writ correct query
li += '<li>' + jsn[key].name + '</li>';
});
};
$('#container').html(li);
})
}
var CheckArr = new Array();
init(CheckArr);
$('#btnFilter').click(function(){
var CheckArr = new Array();
$('input[type=checkbox]').each(function () {
if ($(this).is(':checked')) {
CheckArr.push($(this).attr('value'))
}
});
init(CheckArr);
First of all, you have to verify length of array outside of init function. (for case when function is called for first time).Then, you need to iterate your checkboxes array and search every item in your json array(called jsn) to verify condition you need.
Here is solution:
$(document).ready(function(){
var jsn = [
{
"name":"pack01",
"caplessthan100mb":"False",
"cap100to500mb":"True",
"cap500mbto2g":"False",
"cap2gto10g":"False"
},
{
"name":"pack02",
"caplessthan100mb":"True",
"cap100to500mb":"False",
"cap500mbto2g":"False",
"cap2gto10g":"False"
},
{
"name":"pack03",
"caplessthan100mb":"False",
"cap100to500mb":"False",
"cap500mbto2g":"False",
"cap2gto10g":"True"
},
{
"name":"pack04",
"caplessthan100mb":"False",
"cap100to500mb":"False",
"cap500mbto2g":"True",
"cap2gto10g":"False"
},
{
"name":"pack05",
"caplessthan100mb":"False",
"cap100to500mb":"False",
"cap500mbto2g":"False",
"cap2gto10g":"True"
},
{
"name":"pack06",
"caplessthan100mb":"True",
"cap100to500mb":"False",
"cap500mbto2g":"False",
"cap2gto10g":"False"
},
{
"name":"pack07",
"caplessthan100mb":"False",
"cap100to500mb":"False",
"cap500mbto2g":"False",
"cap2gto10g":"True"
}
];
function init(arr){
var li = '';
if(arr.length==0)
{
$.each(jsn, function (key, value) {
li+= '<li>' + jsn[key].name + '</li>';
});
}
else{
$(arr).each(function (i, v) {
$.each(jsn, function (key, value) {
if(jsn[key][v]=="True")
li+= '<li>' + jsn[key].name + '</li>';
});
});
}
$('#container').html(li);
}
var CheckArr = new Array();
init(CheckArr);
$('#btnFilter').click(function(){
var CheckArr = new Array();
$('input[type=checkbox]').each(function () {
if ($(this).is(':checked')) {
CheckArr.push($(this).attr('value'))
}
});
init(CheckArr);
})
});

There are quite a few things in your code that could use improvement so I've taken the liberty of largely rewriting it (see jsFiddle link below).
1) First thing is in your data (jsn) you are using "False" and "True" instead of false and true. That'll make it hard to write your filter condition because true != "True".
2) It's quite hard to debug your code because the variable names aren't very meaningful. I'd highly recommend putting some energy into improving your variable names especially when code isn't working.
For example:
packsData instead of jsn
checkedBoxes instead of arr
3) If you try to filter within the .each() below you'll run into trouble when it matches more than one filter condition (it'll be displayed more than once).
$(arr).each(function (i, v) {
// this section must be filter "pack's" but i can't writ correct query
li += '<li>' + jsn[key].name + '</li>';
});
Here is a working jsFiddle
I need to find all elements in a page by attribute value only (ignoring the key) using jquery.
Is there a way to do this easily?
Currently, I am just iterating on all elements in the page, on every property etc..
You can use $.expr, Element.attributes, Array.prototype.some()
$.expr[":"].attrValue = function(el, idx, selector) {
return [].some.call(el.attributes, function(attr) {
return attr.value === selector[selector.length - 1]
})
};
// filter element having attribute with `value` set to `"abc"`
$(":attrValue(abc)").css("color", "blue");
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js">
</script>
<div title="abc">abc</div>
<div title="def">def</div>
<div title="ghi">ghi</div>
<div title="jkl">jkl</div>
Use brackets []
var ElementsWithAttributeKeyTest = $('[attributeKey="Test"]');
Or pass an object with the attribute name and value as parameter to this function:
var getElemsByAttribute = function(obj) {
if (obj) {
if (obj.attributeKey && obj.attributeValue) {
return $('[' + obj.attributeKey + '="' + obj.attributeValue + '"]');
}
}
}
var attrObj = {
attributeKey: 'data-color',
attributeValue: 'red'
}
getElemsByAttribute(attrObj).css('color', 'red');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.1/jquery.min.js"></script>
<span data-color="red">Red</span>
<span data-color="red">Red</span>
<span data-color="green">Green</span>
<span data-color="blue">Blue</span>
<span data-color="red">Red</span>
<span data-color="green">Green</span>
If you want to search all attributes values you can use this small plugin:
$.fn.search_by_attr_value = function(regex) {
return this.filter(function() {
var found = false;
$.each(this.attributes, function() {
if (this.specified && this.value.match(regex)) {
found = true;
return false;
}
});
return found;
});
};
and you can use it like this:
$('*').search_by_attr_value(/^some value$/);
Based on this answer
You could define new function take as parameter the value you want to filter with (e.g get_elements_by_value(filter)), then inside this function parse all the elements of the page using $('*').each(), after that parse the attributes of every element el of those elements using attribute attributes like below :
$.each(el.attributes, function(){ })
Then inside the each loop you could make your condition and push the matched values with the passed filter inside matched[] that should be returned.
Check working example below, hope this helps.
function get_elements_by_value(filter){
var matched=[];
$('*').each(function(index,el) {
$.each(el.attributes, function() {
if( this.value===filter )
matched.push(el);
})
})
return $(matched);
}
get_elements_by_value('my_value').css('background-color','green');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div title="my_value">AA</div>
<div title="def">BB</div>
<input type='text' name='my_value' value='CC'/>
<p class='my_value'>DD</p>
<span title="test">EE</span>
I have a button which I want to toggle with ng-show based on the value of my Id.
in my javascript I call my service from on function and then using them from another function.
My issue is when using ng-click I can return the correct Id but when using ng-init it returns the value as undefined.
how do I Invoke and define the Id value from a "onload" event like ng-init?
HTML
<button type="button" class="col button button-small button-dark" ng-click="showMe(ph);" ng-init="showMe(ph);">
Check In
</button>
Javascript
Service Get
$scope.PhaseData = function(Truck) {
var TruckID = window.localStorage['truckid'];
$http.get("http://localhost:53101/TruckService.svc/GetStatusA/" + TruckID)
.success(function(data) {
var PhaseID = null;
var obj = data;
var ar = [];
angular.forEach(obj, function(index, element) {
angular.forEach(index, function(indexN, elementN) {
ar.push({PId: indexN.PId, PhaseId: indexN.fk_Phase, Checkin: indexN.Checkin, Chassis: indexN.ChassisPrep, Floor: indexN.Floor, Body: indexN.Body, Paint: indexN.Paint, PhaseName: indexN.PhaseName });
$scope.ph = ar;
/* $scope.PHID = 1; indexN.PId*/
})
});
})
.error(function(data) {
console.log("failure");
})
};
function
$scope.showMe = function(ph)
{
console.log('2', $scope.ph[0].PId );
console.log('cool');
if ($scope.ph[0].PId >= 1)
{
$scope.show=true;
}
else if($scope.ph[0].PId <= 2)
{
$scope.show=false;
}
}
Change your code to this, may be your HTML render before the value is coming
<button ng-if="ph" type="button" class="col button button-small button-dark" ng-click="showMe(ph);" ng-init="showMe(ph);">Check In</button>
I want to implement the ability to dynamically add comboboxes and I have to use Telerik ComboBox for that. I put this logic into button click.
$('#add-presenter').click(function (e) {
e.preventDefault();
var combobox = '#(Html.Telerik().ComboBox()
.Name("Presenters[" + (Model.Count) + "]")
.BindTo(new SelectList(LeaderList, "ID", "Value"))
.ClientEvents(ev => ev.OnChange("onSelect"))
.DataBinding(bnd => bnd.Ajax().Select("_LoadJournalist", "MonitoringFRadio"))
.Filterable(filter => filter.FilterMode(AutoCompleteFilterMode.StartsWith))
.HtmlAttributes(new { style = "width:320px;vertical-align:middle;" }))';
combobox = combobox.split('Presenters[' + index + ']').join('Presenters[' + (index + 1) + ']');
index++;
$('#presenters-block').append(combobox);
}
This code renders in browser as this:
$('#add-presenter').click(function (e) {
e.preventDefault();
var combobox = '<div class="t-widget t-combobox t-header" style="width:320px;vertical-align:middle;"><div class="t-dropdown-wrap t-state-default"><input class="t-input" id="Presenters[0]-input" name="Presenters[0]-input" type="text" /><span class="t-select t-header"><span class="t-icon t-arrow-down">select</span></span></div><input id="Presenters[0]" name="Presenters[0]" style="display:none" type="text" /></div>';
combobox = combobox.split('Presenters[' + index + ']').join('Presenters[' + (index + 1) + ']');
index++;
$('#presenters-block').append(combobox);
combobox = $('#Presenters\\['+index+'\\]').data('tComboBox');
});
The problem is in data-binding. This code generates proper HTML, but newly added list doesn't "drop"
When I do combobox = $('#Presenters\\['+index+'\\]').data('tComboBox'); for newly added item I get undefined (it exists, but data isn't set), so combobox.dataBind(dataSource) approach doesn't work.
Ok, I tried, but failed to do this without postback. Here's rough solution to the problem: do ajax request and replace content with partial view:
The Partial view:
#model List<int>
#{
var LeaderList = ViewData["LeaderList"] as List<ListItem>;
}
<div id="presenters-ajax-wrapper">
<div id="presenters-block">
#(Html.Telerik().ComboBox()
.Name("Presenters[0]")
.BindTo(new SelectList(LeaderList, "ID", "Value"))
.ClientEvents(ev => ev.OnChange("onSelect"))
.DataBinding(bnd => bnd.Ajax().Select("_LoadJournalist", "MonitoringFRadio"))
.Filterable(filter => filter.FilterMode(AutoCompleteFilterMode.StartsWith))
.HtmlAttributes(new { style = "width:320px;vertical-align:middle;" }))
#for(int i=1; i<Model.Count; i++)
{
var item = LeaderList.FirstOrDefault(l => l.ID == Model[i]);
var value = item != null ? item.Value : "";
#(Html.Telerik().ComboBox()
.Name("Presenters[" + i + "]")
.Value(value)
.BindTo(new SelectList(LeaderList, "ID", "Value"))
.ClientEvents(ev => ev.OnChange("onSelect"))
.DataBinding(bnd => bnd.Ajax().Select("_LoadJournalist", "MonitoringFRadio"))
.Filterable(filter => filter.FilterMode(AutoCompleteFilterMode.StartsWith))
.HtmlAttributes(new { style = "width:320px;vertical-align:middle;" }))
}
</div>
<button id="add-presenter" class="t-button">+</button>
<script type="text/javascript">
var index = #(Model.Count == 0 ? 0 : Model.Count-1);
$('#add-presenter').click(function (e) {
e.preventDefault();
index++;
var msg = $('#monitForm').serialize();
$.ajax({
url: '#Url.Action("_GetPresenters","MonitoringFRadio")'+'?count='+(index+1),
data: msg,
type: 'POST',
success: function(data) {
$('#presenters-ajax-wrapper').html(data);
}
});
});
</script>
</div>
Action:
[HttpPost]
public virtual ActionResult _GetPresenters(EditableMonitoring model, int count)
{
//some logic here...
return PartialView("EditorTemplates/Presenters", model.Presenters);
}
Well, probably it would be better to create another partial view which would render a single combobox, instead of redrawing all of them...
