I am using an ajax function to append a comment to a a list of existing comments. I have the append to working, but after I append the comment is still in the text field. I am trying to figure out how to clear the text field after the append to. Any pointers on how to go about this would be greatly appreciated.
$('.new_question_comment').on('submit', function(event) {
event.preventDefault();
$form = $(event.currentTarget);
$.ajax({
type: "POST",
url: $form.attr('action'),
data: $form.serialize(),
dataType: "json",
success: function(data) {
$form.siblings().first().append("<h6>"+ "-" + data.body + "</h6><br>")
}
});
});
In your success callback function add the following after you append the data:
$form.each (function() { this.reset(); });
This will reset the form values back to their default.
jsFiddle example
You could also use the native JavaScript form reset function:
$form[0].reset();
If the specific text field has an ID, say "text", clear it directly:
document.getElementById('text').value='';
You can clear the entire form too:
document.getElementById('form').reset();

Before submitting with Ajax, I am changing the ids of all inputs on the form, due to a need.
The problem is when I submit using Ajax, I need to replace the html of all fields in the form using the replaceWith function, but it is not doing that. It is simply changing the html, but it seems to be keeping the original html when I inspect it in the browser.
HTML should be replaced as shown in image 2.
Why can't HTML be replaced correctly? Shouldn't the replaceWith function be used for such a situation?
var genericModal = getLastGenericModalObject();
var frmFormaContato = genericModal.find('.frm-create-edit');
var valdata = frmFormaContato.serialize();
$.ajax({
url: url,
type: "POST",
traditional: true,
data: valdata,
headers: { "RequestVerificationToken": $('input[name="__RequestVerificationToken"]').val() },
success: function (data) {
frmFormaContato.replaceWith(data);
stopLoadGlobal();
},
error: function (e) {
stopLoadGlobal();
redirectToError(e.status);
return false;
}
});
Thank you :)
The solution was to change the IDs before replacing the HTML according to the DOM.
var dataChanged = changeIds($(data));
frmFormaContato.replaceWith(dataChanged);
I'm currently working on a project using Laravel platform.
I'm trying to delete data from a model asynchronously using ajax. And when all is done my data should be removed from the table. My code runs perfectly, data are being removed from my database , yet "tr" elements arent really faded or removed. Here is my code :
ajax sucess not really working.
$(document).on('click', '.btn-remove-interview' , function() {
var id = $(this).attr('data-interview-id');
$.ajax({
url: './manage/interviews/destroy/'+id ,
type: 'post',
dataType: 'json',
data: id,
success: function (data) {
$(this).parents("tr").remove();
}
});
});
Use
$(this).closest('tr').remove();
Instead of
$(this).parents("tr").remove();
The problem is that the success function callback within your ajax request no long refers to the button when you use this. You need to get an explicit variable to the button if you want to use it.
$(document).on('click', '.btn-remove-interview' , function() {
// Get this button as a variable so we can use it later
var el = $(this);
var id = $(this).attr('data-interview-id');
$.ajax({
url: './manage/interviews/destroy/'+id ,
type: 'post',
dataType: 'json',
data: id,
success: function (data) {
$(el).parents("tr").remove();
}
});
});
Solution was by removing dataType json . My function doesnt return any data .
I have to recreate a form that was originally created using Jotform - it is here. I am struggling in one area. It is a pretty simple form, the only caveat being the ability to duplicate a form field form multiple entries. That part can be seen here. When the form is duplicated, I need to submit the form data as a JSON array. In the fiddle, I didn't put the regular form fields, here is how they and the cloned field need to submit the data.
q2_fullName[first]:test
q2_fullName[last]:test
q1_currentCommission1:[{"Instruments":"a","Commissions":"1","Margins":"a"},{"Instruments":"b","Commissions":"2","Margins":"b"},{"Instruments":"c","Commissions":"3","Margins":"c"}]
normally in my $.ajax handler, I just serialize the data, but that doesn't work in creating the json array for the cloned fields. Normally like so:
submitHandler: function(form) {
var dataString = $(form).serialize();
$.ajax({
type:'POST',
url: form.action,
data: dataString,
dataType: "json",
beforeSend: function(data){
//before send
},
success: function(data){
//success function
}
});
return false;
},
I need to somehow serialize the non cloned fields (I think) and create a json array out of the cloned values and assign them a key name
You can build the post data and the json string like this :
var data = {
// get/set the firstname etc
"q2_fullName":{
"first":"", // get firstname ie $("#first_2").val(),
"last":""
},
"q1_currentCommission1" :""
},
commisions = [];
$('.InsContain').each(function() {
var $inputs = $(this).find('input');
commisions.push({
"Instruments" : $inputs.eq(0).val(),
"Commissions" : $inputs.eq(1).val(),
"Margins" : $inputs.eq(2).val()
});
});
data.q1_currentCommission1 = JSON.stringify(commisions);
Posted data :
q2_fullName[first]:aaa
q2_fullName[last]:123
q1_currentCommission1:[{"Instruments":"1","Commissions":"1","Margins":"1"}]
Update fiddle here
I have two buttons on the form I'm getting, this first piece of coce allow me to know which was the button clicked by getting the id of it.
var button;
var form = $('.register_ajax');
$('#vote_up, #vote_down').on("click",function(e) {
e.preventDefault();
button = $(this).attr("id");
});
and this other send the form data through AJAX using the info already obtained from the button using the script above.
form.bind('submit',function () {
$.ajax({
url: form.attr('action'),
type: form.attr('method'),
cache: false,
dataType: 'json',
data: form.serialize() + '&' + encodeURI(button.attr('name')) + '=' + encodeURI(button.attr('value')) ,
beforeSend: function() {
//$("#validation-errors").hide().empty();
},
success: function(data) {
if(data.message == 0){
$("#fave").attr('src','interactions/favorite.png');
$("#favorite").attr('value',1);
console.log(data.errors);
}
if(data.message == 1)
{
$("#fave").attr('src','interactions/favorite_active.png');
$("#favorite").attr('value',0);
}
if(data.message == "plus")
{
$("#vote_up").attr('class','options options-hover');
$("#vote_down").attr('class','options');
console.log(data.message);
}
if(data.message == "sub")
{
$("#vote_down").attr('class','options options-hover');
$("#vote_up").attr('class','options');
console.log("sub");
}
},
error: function(xhr, textStatus, thrownError) {
console.log(data.message);
}
});
return false;
});
The problem is that the data is not being passed to the ajax function, the button info is being saved on the button var, but it's not being obtained at time on the ajax call to work with it (or at least that is what I think). I'd like to know what can I do to make this work, any help appreciated.
1st edit: If I get the button data directly like button = $('#vote_up'); it doesn't work either, it only works if I get the button directly like this but without using the function.
2nd edit: I found the solution, I posted below.
var button is in the scope of the .on('event', function(){})
You need to declare the variable in the shared scope, then you can modify the value inside the event callback, i.e.
var button,
form = $('.register_ajax');
$('#vote_up, #vote_down').on("click",function(e) {
e.preventDefault();
button = $(this).attr("id");
});
You are being victim of a clousure. Just as adam_bear said you need to declare the variable outside of the function where you are setting it, but you are going to keep hitting these kind of walls constantly unless you dedicate some hours to learn the Good Parts :D, javascript is full of these type of things, here is a good book for you and you can also learn more from the author at http://www.crockford.com/.
I Found the solution, I just changed a little bit the click function like this:
var button;
var form = $('.register_ajax');
var data = form.serializeArray();
$('#vote_up, #vote_down').on("click",function(e) {
e.preventDefault();
button = $(this).attr("id");
data.push({name: encodeURI($(this).attr('name')), value: encodeURI($(this).attr('value'))});
form.submit();
});
using e.preventDefault(); and form.submit(); to send the form. also I changed the data.serialize to serializeArray(); because it's more effective to push data into the serializeArray(). in the second script I just changed the data.serialize() and used the data variable that I already filled with the serializeArray() and the data.push():
form.bind('submit',function () {
alert(button);
$.ajax({
url: form.attr('action'),
type: form.attr('method'),
cache: false,
dataType: 'json',
data: data,
//here goes the rest of the code
//...
});
return false;
});
it worked for me, it solved the problem between the click and submit event that wasn't allowing me to send the function through ajax.
first a little bit of documentation from the jQuery validation plugin:
"Use submitHandler to process something and then using the default submit. Note that "form" refers to a DOM element, this way the validation isn't triggered again."
submitHandler: function(form) {
$.ajax({
type: 'POST',
url: form.action,
data: 'current_password=' + form.current_password + '&new_password=' + form.new_password,
success: function(){
alert("succes");
}
});
}
So, naturally my ingenious piece of code isn't working. I'm trying to access the 'action' attribute and the two input fields from the form object, with no luck. How am I supposed to do this?
Try this instead:
submitHandler: function(form) {
$.ajax({
type: 'POST',
url: $(form).attr('action'),
data: { current_password : form.current_password.value,
new_password: form.new_password.value }
success: function(){
alert("succes");
}
});
}
Currently instead of submitting the values of the elements it's literally calling a toString on them, so just add .value to get the values. Also we're passing data as an object here so it gets encoded, otherwise if for example the password had a & in it, the post wouldn't be correct.
