I am trying to reset the form to blank values in the input textboxes after the data filled in the textbox have been searched.
<form id="myForm" class="mt-5" asp-controller="Leave" asp-action="GetAllLeaves">
<div class="form group col-md-6">
<label>Employee </label>
<div class="col">
<input type="hidden" id="employeeId" name="employeeId" />
<input type="text" name="employeeName" id="employeeName" value="#ViewData["CurrentFilterE"]" />
</div>
</div>
<button type="submit" class="btn btn-outline-success">Search</button>
<button type="reset" id="reset" class="btn btn-outline-primary">Reset</button>
</form>
I have tried bunch of different javascripts but none of them work after the search has been completed. They work fine before the search button is clicked. I am aware that there are questions already asked about this here and I have tried those codes but they don't work for me.
These are the different codes that I have tried. They don't work after the search button has been hit. Even refreshing the page does not delete the data in the input boxes.
function myFunction() {
document.getElementById("myForm")[0].reset();
};
$("#reset").click(function () {
$(this).closest('form').find("input[type=text], textarea").val("");
});
document.getElementById("reset").onclick = () => {
document.getElementById("myForm").reset()
};
let inputs = document.querySelectorAll('input');
document.getElementById("reset").onclick = () => {
inputs.forEach(input => input.value ='');
}
in your post method you need to have an IactionResult return type method and then you need to pass property name to ModelState.Remove method, not the value.
Either pass the property name in string, eg. ModelState.Remove("PropertyName"); or in the newer .NET framework, you can use nameof() keyword, eg. ModelState.Remove(nameof(model.Property));
The HTMLFormElement.reset() method restores a form element's default values. This method does the same thing as clicking the form's reset button. If a form control (such as a reset button) has a name or id of reset it will mask the form's reset method. It does not reset other attributes in the input, such as disabled.
https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement/reset.
Your default input value = "#ViewData["CurrentFilterE"]". Reset method restores a form element's default values.
This will help to reset the input:
html:
<form id="myForm">
<input type="text" name="employeeName" id="employeeName" value="test" />
<button id="reset" class="btn btn-outline-primary">Reset</button>
</form>
js:
document.getElementById("reset").onclick = function(e) {
document.getElementById("employeeName").value = "";
}
I ended up using the following
$("#reset").click(function () {
// this for normal <input> text box
$('#employeeName').attr("value", "");
//this for checkbox
document.getElementById('searchAprroved').removeAttribute('checked');
});

I have the following code:
<form id="buttonForm" action = "/goSomeWhere" method="post" >
<input type="submit" name="bnext" value="Next Page" >
<input type="submit" name="bprevious" value="Previous Page" >
</form>
When either one of this two buttons are submitted I receive "bnext" or "bprevious" values in Django View request.POST so I can further construct the logic that I need.
But when I'm trying to insert some javascript for the second button I loose those values:
<input type="submit" name="bnext" value="Next Page" >
<input type="submit" name="bprevious" id="bpid" onclick="disable()" value="Previous Page" >
function disable()
{
document.getElementById("bpid").disabled = true;
document.getElementById("buttonForm").submit();
}
There is a way to do this and still receiving input names values ?
Sorry I didn't fully understood that what you are trying to do
If you are trying to stop form submission then:
function disable() {
document.getElementById("bpid").disabled = true;
document.getElementById("buttonForm").preventDefault();
}
If you want that client should not click previous button again then, it is best to change inputType submit to hidden:
function disable() {
document.getElementById("bpid").type="hidden";
document.getElementById("buttonForm").submit();
}
Or
create new <input type=hidden>, set name values ,append to form and submit it:
function disable() {
document.getElementById("bpid"). disabled=true;
newip= document.createElement("input");
newip.type="hidden";
newip.name="bprevious";
newip.value="Previous Page";
document.getElementById("buttonForm").appendChild(newip);
document.getElementById("buttonForm").submit();
}
try to use button instead input like this
<button name="bprevious" id='bpid' onclick='disable()' value="Previous Page">Previous Page</button>
I have a button that opens an ngDialog.openConfirm. Within that dialog I have a form, which includes a textarea which is required and needs to be a minimum 20 characters.
Here is a simplified version of my code:
someFunction() {
let newScope = $scope.$new();
newScope.vm = vm;
ngDialog.openConfirm({
scope: newScope,
template: 'componentDescription.html'
})
}
And my html:
<form role="form" name="subForm">
<textarea name="compDesc"
required="true"
ng-minlength="20"
ng-model="vm.compDesc">
</textarea>
<button type="button" ng-click="confirm(0)">Submit</button>
<button type="button" ng-click="closeThisDialog(0)">Cancel</button>
</form>
I would like for the Dialog to only be submitted if the form is valid.
I tried to do this by creating a function in my controller , but that has trouble accessing the form/closing the dialog.
Any ideas?
UPDATE:
I've changed my html like so:
<form role="form" name="subForm" novalidate ng-submit="confirm(0)">
<textarea name="compDesc"
required="true"
ng-minlength="20"
ng-model="vm.compDesc">
</textarea>
<button type="submit">Submit</button>
<button type="button" ng-click="closeThisDialog(0)">Cancel</button>
</form>
This works on the first click, which brings up my error messages, but on the second click it submits the form even though it's invalid. Seems that whenever the error messages are displayed the submit button ignores the validation.
You can manually decide whether to call $scope.confirm() or not,
Pass validation then call $scope.confirm().
Not Pass validation, don't call $scope.confirm().
e.g.
Template:
<button type="button" ng-click="ok(0)">Submit</button>
Controller:
$scope.ok = function () {
if(!validationHasPassed()){
//errorMsg.push('xxx')
return false;
}
$scope.confirm();
};
Simply you can add ng-disabled option with your form name
<button type="button" ng-disabled="subForm.$invalid" ng-click="confirm(0)">Submit</button>
you can disable submit button if length of input string is less then 20
<button type="button" ng-disabled="vm.compDesc.length < 20" ng-click="confirm(0)">Submit</button>
you can also display an error message below text area so users can understand why submit button is not enabled
<form role="form" name="subForm">
<textarea name="compDesc"
required="true"
ng-minlength="20"
ng-model="vm.compDesc">
</textarea>
<p ng-show="vm.compDesc.length < 20" style="color:#cc5965">Description should be at least 20 characters</p>
<button type="button" ng-click="confirm(0)">Submit</button>
<button type="button" ng-click="closeThisDialog(0)">Cancel</button>
</form>
I am editing some javascript that has a search box with a variable as follows
var secondSearchTerm = $('#2nd-search').val();
In the HTML code '2nd-search' has a placeholder 'Enter search term'
I also have a reset button that clears the search as follows:
$("#2nd-reset-btn").on("click", function () {
return myNetwork.resetSecondSearch();
})
What I would like to do is to get the search box to re-populate with the placeholder when reset is clicked. Right now the last entered term remains in the search box.
Any ideas on how I can edit the code to do this?
Many thanks!
hi refer this link https://plnkr.co/edit/EtLmby5BdD5Yn70EIBRD?p=preview
js
// Add your javascript here
$(function(){
$("#reset").on("click", function () {
return $('#username').val('');
});
});
html
<input type="text" name="name" id = "username" placeholder="uname"/>
<button id="reset">Reset </button>
All you need to do is set the value to blank & take the focus away from the input(As some browsers hide placeholder on focus). The placeholder will be visible again. Try the following:
$("#2nd-reset-btn").on("click", function () {
secondSearchTerm.blur();
return secondSearchTerm.val('');
})
You can do it with pure JS only
Given the initial value
function reset() {
var initialValue = 'Enter your search term.';
var query = document.getElementById('myquery');
query.value = initialValue;
}
<input type="text" id="myquery" />
<input type="button" id="reset" onclick="reset()" value="Reset" />
Given the placeholder
function reset() {
var query = document.getElementById('myquery');
query.value = '';
}
HTML
<input type="text" id="myquery" />
<input type="button" id="reset" onclick="reset()" value="Reset" />
I would like to copy the value from an input in one form to the value of an input(with the same name) of the next form down. The forms and inputs are named the same. All it needs to do is copy the value of the title input to the title input one form down.
<form>
<input name="file" value="1.xml">
<input name="title" id="title" value="Smith">
<input type="submit" id="copy-down" value="copy">
</form>
<form>
<input name="file" value="2.xml">
<input name="title" id="title" value="Anderson">
<input type="submit" id="copy-down" value="copy">
</form>
etc...
In this case when the top "copy" button is clicked I would like jquery to overwrite Anderson with Smith.
$('#title').attr('value'));
Gives me Smith but I'm not sure what to do with that value once I have it.
Change HTML to this:
<form>
<input name="file" value="1.xml">
<input name="title" id="title1" value="Smith">
<input type="submit" id="copy-down1" value="copy">
</form>
<form>
<input name="file" value="2.xml">
<input name="title" id="title2" value="Anderson">
<input type="submit" id="copy-down2" value="copy">
</form>
Javascript:
function copyHandler() {
var copyVal = document.getElementById("title1").value;
var replaceInput = document.getElementById("title2");
replaceInput.value = copyVal;
}
document.getElementById("copy-down1").onclick = function(){
copyHandler();
return false;
}
Some notes:
This is so straightforward in vanilla javascript that I didn't add the jQuery code.
You should never assign multiple elements to the same ID, class or name can be used for that purpose.
The return false; portion of the onclick function is necessary so that the form doesn't reload when you click your submit button.
Let me know if you have any questions.
you can try
$(document).ready(function(){
$('form').on('submit', function(e){
e.preventDefault();
var GetNameAttr = $(this).find('input:nth-child(2)').attr('name');
var GetTitleValue = $(this).find('input:nth-child(2)').val();
var NextFormNameAttr = $(this).next('form').find('input:nth-child(2)').attr('name');
if(NextFormNameAttr == GetNameAttr){
$(this).next('form').find('input:nth-child(2)').val(GetTitleValue );
}
});
});
Note: this code will change the second input value in next form with
the second input value of form you click if the name is same .. you
can do the same thing with the first input by using :nth-child(1)
Demo here
if your forms dynamically generated use
$('body').on('submit','form', function(e){
instead of
$('form').on('submit', function(e){
for simple use I create a function for that
function changeNextValue(el , i){
var GetNameAttr1 = el.find('input:nth-child('+ i +')').attr('name');
var GetTitleValue1 = el.find('input:nth-child('+ i +')').val();
var NextFormNameAttr1 = el.next('form').find('input:nth-child('+ i +')').attr('name');
if(NextFormNameAttr1 == GetNameAttr1){
el.next('form').find('input:nth-child('+ i +')').val(GetTitleValue1);
}
}
use it like this
changeNextValue($(this) , nth-child of input 1 or 2);
// for first input
changeNextValue($(this) , 1);
// for second input
changeNextValue($(this) , 2);
Working Demo
I'm creating a simple website and a html page on it which contains a table that shows products. I load this table using AJAX and it work properly. Here is a screenshot:
Under the table I have buttons which perform CRUD operations using AJAX.
They communicate to a php script on a server outside of my domain using GET method.
When I click on Add product it opens a form with a button that whose onclick event calls a function which adds a product using AJAX. But, when I click, the whole page reloads and the product is not added. If I put the value that says wheter the call is async to false, it works as intended and the product is added to the table, however that is not the point of AJAX.
This is my code for adding a product(delete and update are almost the same).
<div id="addProductPopup">
<div id="popupContact">
<form id="form" method="post" name="form">
<img id="close" src="/servis/Resursi/Slike/close.png" onclick ="hide('addProductPopup');">
<h2>Dodavanje proizvoda</h2>
<hr>
<input id="name" name="naziv" placeholder="Naziv proizvoda" type="text" required>
<input id="kolicina" name="kolicina" placeholder="Količina proizvoda" type="text" required>
<input id="url" name="url" placeholder="URL slike" type="text" required>
<input type="submit" value="Pošalji" class="popupButtons" onclick="addProduct()">
</form>
</div>
When I click on submit this function is called:
function addProduct(){
var isValid = true;
var url = "http://zamger.etf.unsa.ba/wt/proizvodi.php?brindexa=16390";
var amount = document.form.kolicina.value;
var naziv = document.form.naziv.value;
var slikaurl = document.form.url.value;
var validity = validateFields(naziv, slikaurl, amount);
if(!validity) return false;
var product = {
naziv: naziv,
kolicina: amount,
slika: slikaurl
};
var requestObject = new XMLHttpRequest();
requestObject.onreadystatechange = function(event) {
if (requestObject.readyState == 4 && requestObject.status == 200)
{
loadProducts();
event.preventDefault();
}
}
requestObject.open("POST", url, true);
requestObject.setRequestHeader("Content-type","application/x-www-form-urlencoded");
requestObject.send("akcija=dodavanje" + "&brindexa=16390&proizvod=" + JSON.stringify(product));
}
It is because you are not preventing the default action of the submit button click.
You can return false from an event handler to prevent the default action of an event so
<input type="submit" value="Pošalji" class="popupButtons" onclick="addProduct(); return false;">
But since you have a form with a submit button, I think it will be better to use the submit event handler like
<form id="form" method="post" name="form" onsubmit="addProduct(); return false;">
....
<input type="submit" value="Pošalji" class="popupButtons">
Your problem is that your submit button still executes a real submit. You could change your addProducts method. The method have to return false to prevent the real submit.
Submit button performs default Submit action for HTML code.
Try to change Submit tag into Button tag. Or after AddProduct() in OnClick JS Action put
return false;
Simple Change put input type="button" instead of tpye="submit"
<input type="button" value="Pošalji" class="popupButtons" onclick="addProduct()">
