Here is the script i'm using to append name input field-
<script>
$(document).ready(function() {
$("#add").click(function() {
var someId = document.getElementById('someId').value;
var name = document.getElementById('name').value;
$('.print_box').append('<div class="' + someId + '"> <tr> <td> <input type="button" ref="'+someId+'" class="remove_button" value="Remove"></td> <td><input type="text" multiple name="name[]" value="' + name + '" </td> </tr>
});
});
</script>
Now I want to call remove button from a separate standalone script like-
<script>
$(document).ready(function() {
$(".remove_button").click(function() {
var getRemoveID = $(this).attr('ref');
$("." + getRemoveID + "").remove();
});
});
</script>
But this isn't working. It only works when remove function is included with append like-
<script>
$(document).ready(function() {
$("#add").click(function() {
var someId = document.getElementById('someId').value;
var name = document.getElementById('name').value;
$('.print_box').append('<div class="' + someId + '"> <tr> <td> <input type="button" ref="' + someId + '" class="remove_button" value="Remove"></td> <td><input type="text" multiple name="name[]" value="' + name + '" </td> </tr>
$(".remove_button").click(function() {
var getRemoveID = $(this).attr('ref');
$("." + getRemoveID + "").remove();
});
});
});
</script>
Now, How can I seperate those 2 function? i mean calling remove button outside that append script??
Just use on
$("body").on("click", ".button", function() {
alert("click")
});

This is not how you solve it. You are going in wrong direction. The problem here is that you are trying to handle events for the elements which are being added on the DOM dynamically.
So you need to handle events like (click, mouseover etc) for those elements in this way
$(document).on('click', '.remove_button', function(){
//Code to handle that event when click on remove_button
});

I am trying to execute the function that was created separately called uploads.js . This javascript file is a custom image uploader function to be used in Wordpress. I was able to run that javascript file whenever i create a new button just by the of the HTML by sending the needed parameters.
There is a part where i created a dynamic button creation function using jquery, where whenever a 'PLUS' sign button is pressed, that function will trigger and a new button is added. The id of that button is automatically incremented by one.
The problem here is, whenever i click on the button that was created not by using the dynamic button function, it was able to execute the uploads.js function. But the dynamic created buttons are not able to. It seems like the id of the dynamic button was not detected. I even inspect the element of that page, the id that was sent is exactly the same from what I have sent as a parameter to the uploads.js function.
Is there something that i have missed or I have done wrong? Below are the codes:
HTML
<tr class="form-field">
<th scope="row">
<label for="component1"> Component 1</label>
<br></br>
<input type='button' class="button button-large" value='+' id='addButton'>
<input type='button' class="button button-large" value='-' id='removeButton'>
<input type='button' class="button button-large" value='Get TextBox Value' id='getButtonValue'>
</th>
<td>
<div id='TextBoxesGroup'>
<div id="ImageDiv1">
<input id="section2_1" class="button" type="button" value="Upload Image" name="upload_s2_1"/>

<div id="TextBoxDiv1">
<label>Title #1 : </label>
<input type='text' id='title1' />

Other button(like #section2_2, #section2_3 ...) maybe not exist, When function dynamic_image run.
Then below code cannot have meaning.
dynamic_image('#section2_2' , '#section2_text2');
// cannot find #section2_2 , because not yet added
Try this.
// function is called when input.button(like #section2_1, #section2_2 ...) on #TextBoxesGroup clicked

custom_uploader.on('select', function() {

//Open the uploader dialog

See example
indicate actually like following
$('#TextBoxesGroup').on('click','input.button',function(e){
var $clickedInput = $(this);// JQuery Object of section2_2
var clickedInputId = $clickedInput.attr('id'); // section2_2
var indicateKey = clickedInputId.substring(10,clickedInputId.length);// 2
var neededTextId = 'section2_text'+indicateKey ; //section2_text2
var $neededText = $("#" +neededTextId ); // JQuery Object of section2_text2
// run logic what you want to do

I am trying to detect the current button click to assign values to its respective textboxes. Each time I select any of the button, it will detect the first button click and assign the value to the first textbox. Meaning to say that, the second and third button values are assigned to the first textbox. The upload_textbox variable is not changing its value.
I did some error testing, when upload_textbox variable enters custom_uploader.on('select', function(), the value stays and will not change. I am not sure on why it doesn't.
What have I done wrong here? Below are my codes:
function dynamic_image( button )
{
var custom_uploader;
$(button).on('click','input.button',function(e)
{
e.preventDefault();
var $clickedInput = $(this);// JQuery Object of section2_2
var clickedInputId = $clickedInput.attr('id'); // section2_2
var upload_textbox = '#' + 'upload_image_' + clickedInputId;
//If the uploader object has already been created, reopen the dialog
if (custom_uploader) {
custom_uploader.open();
return;
}
//Extend the wp.media object
custom_uploader = wp.media.frames.file_frame = wp.media(
{
title: 'Choose Image',
button: {
text: 'Choose Image'
},
multiple: false
});
//When a file is selected, grab the URL and set it as the text field's value
custom_uploader.on('select', function()
{
attachment = custom_uploader.state().get('selection').first().toJSON();
$(upload_textbox).val(attachment.url);
//console.log(upload_textbox);
});
//Open the uploader dialog
custom_uploader.open();
})

Then I suspect this could be the culprit.
//If the uploader object has already been created, reopen the dialog
if (custom_uploader) {
custom_uploader.open();
return;
}
This would always give you instance of first custom_uploader object.
Try to destroy the previous instance and generate new one.
There might be issue with the event binding within dynamic_image method.
Try
$(button).live('click',function(e) (deprecated as of jQuery 1.7 though)
or
$( document ).on( 'click', button, data, function(e)
instead of
$(button).on('click','input.button',function(e)
I hope it helps.
Can you try following.
$(button).change(function(){
//Write code here
});
I have solved my question. The culprit behind this was the custom_uploader mentioned by #Aman. There was a return statement there where it made the function not to take the new value that has been replaced. After doing so, the custom_uploader opens twice because there is two statement of it which it was called. Did it into an if else statement and had it the way I wanted. Below is my updated code.
function dynamic_image( button )
{
var custom_uploader;
var upload_textbox;
$(button).on('click','input.button',function(e)
{
e.preventDefault();
var $clickedInput = $(this);
var clickedInputId = $clickedInput.attr('id');
upload_textbox = '#' + 'upload_image_' + clickedInputId;
//Extend the wp.media object
custom_uploader = wp.media.frames.file_frame = wp.media(
{
title: 'Choose Image',
button: {
text: 'Choose Image'
},
multiple: false
});
//When a file is selected, grab the URL and set it as the text field's value
custom_uploader.on('select', function()
{
attachment = custom_uploader.state().get('selection').first().toJSON();
$(upload_textbox).val(attachment.url);
});
if (custom_uploader) {
custom_uploader.open();
}else
//Open the uploader dialog
custom_uploader.open();
})
}
#Aman, you have mentioned about optimizing it. It seems quite fast at the moment. Maybe if there is a way to optimize it for the better, it would be a great help.
Thank you all, #Regent, #Aman, #Bhushan Kawadkar, #Arindam Nayak, #Raj
I'm looking for help to rename the name attributes of some fields created dynamically.
Now, my code assigns new values to the added fields (it increments according to the length of the div) but the problem appears when I delete a field, I don't know how to rename the remaining according to the number of fields deleted.
jQuery:
$(document).ready(function () {
$("#add").click(function () {
var intId = $("#reglas div").length;
var fieldWrapper = $('<div></div>', {
class: 'fieldwrapper',
id: 'field' + intId
});
var fPath = $('<input align="left" type="text" placeholder="Path" class="reglas_wrapper" id="path" name="field1_' + intId + '" required /> ');
var fTTL = $('<input type="text" class="reglas_wrapper" placeholder="TTL" id="ttl" name="field2_' + intId + '" required />');
var removeButton = $('<input align="right" type="button" id="del" class="remove" value="-" /> <br><br>');
removeButton.click(function () {
$(this).parent().remove();
});
fieldWrapper.append(fPath);
fieldWrapper.append(fTTL);
fieldWrapper.append(removeButton);
$("#reglas").append(fieldWrapper);
});
$("#cache").each(function () {
$(this).qtip({
content: {
text: $(this).next('.tooltiptext')
}
});
});
});
$('#formsite').on('submit', function (e) {
//prevent the default submithandling
e.preventDefault();
//send the data of 'this' (the matched form) to yourURL
$.post('siteform.php', $(this).serialize());
});
HERE'S MY FULL CODE: http://jsfiddle.net/34rYv/131/
You will want an incrementor. Check out this updated fiddle.
Here is the beginning of the code:
$(document).ready(function() {
var myIncr = 0;
$("#add").click(function() {
myIncr++;
var intId = myIncr;
You can add a class or id to each input field, and then depending on that class or id add the name as
<input type="text" class="something" />
Use this jQuery:
var classval = $('input[type=text]').attr('class'); // get class..
// now add the name as
$(this).attr('name', classval);
You can have as many inputs, they will be added the name depending on their class or id!
So even if the input fields are deleted, you will still have the class attributes in the control!
Suppose this is the prepare table below. and each of 3 row there was a textbox and beside them there where 2 buttons the + or add and - for delete. when i click + in a row, a new textbox will be generated and when i click - the textbox will delete. like the sample below:
Could anyone suggest the snippet for this step or procedure?
Thank you
you could write something on these lines:
<script type="text/javascript">
$(document).ready(function(){
var counter = 2;
$("#addButton").click(function () {
if(counter>10){
alert("Only 10 textboxes are allowed");
return false;
}
var newTextBoxDiv = $(document.createElement('div'))
.attr("id", 'TextBoxDiv' + counter);
newTextBoxDiv.after().html('<label>Textbox #'+ counter + ' : </label>' +
'<input type="text" name="textbox' + counter +
'" id="textbox' + counter + '" value="" >');
newTextBoxDiv.appendTo("#TextBoxesGroup");
counter++;
});
$("#removeButton").click(function () {
if(counter==1){
alert("No more textbox to remove");
return false;
}
counter--;
$("#TextBoxDiv" + counter).remove();
});
});
</script>
If you do not want to create the div on the fly, you can find the id of your last table row, add 1 to it, create the table row, and then append the textbox creation html to it.
Assuming the html structure is as follows
<table border = "1">
<thead>
<tr><td> Text Boxes </td></tr>
</thead>
<tbody>
<tr><td><button class="add-text-box">+</button><button class="remove-text-box">-</button></td></tr>
<tr><td><button class="add-text-box">+</button><button class="remove-text-box">-</button></td></tr>
<tr><td><button class="add-text-box">+</button><button class="remove-text-box">-</button></td></tr>
</tbody>
the following jquery snippet should work
$(".add-text-box").click(function(){
$(this).parent().prepend(" <input class='text-box' /> <br>");
});
$(".remove-text-box").click(function(){
textboxes = $(this).parent().find('.text-box');
$(textboxes).last().remove();
if (textboxes.length === 0) {
$(this).siblings().remove();
$(this).remove();
}
});
You can see it in action here
After appending table I am checking on button click event. Javascript alert is working but jQuery click event is not working.
I cannot seem to find my mistake.
$("#inputcon").change(function(e){
if($(this).attr('checked')){
$(this).val('TRUE');
}else{
$(this).val('FALSE');
}
if($(this).val() == 'TRUE'){
$("div#Add").append(' <table id="inputT" style=""> <tr> ' +

}
});
$("#inconbutt").click(function() {
alert("add");
var i1 = $("#icname").val() ;
var pname = $("#pname").val();
var dtype = $("#datatype").val();
var itype = $("#inputtype").val() ;
alert(i1);
alert(pname);
alert(dtype);
alert(itype);
/* $.ajax({

}
}); */
});
The jQuery function you created with .click at bind at the start of the load and your input is being placed after that. So jQuery doesn't recognize the event and your function isn't called.
Try using dynamic binding functions such as:
$.live(/*yourevent*/'click', function(){
// your function
});
OR
$.delegate(/*selector*/, 'click', function(){
//your function
});
OR if you are using newer version of jQuery 1.7+ then you can also use
$.on('click', /*selector*/, function(){
//your function
});
You can't bind an event handler directly to an element that doesn't exist yet. But you can use a delegated event handler bound to the parent element of the element that will be created later:
$("div#Add").on("click", "#inconbutt", function() {
// your code here
});
With that syntax of .on(), jQuery will process any click within the parent "div#Add" element, and test whether it occurred on an element that matches the "#inconbutt" selector in the second parameter. If it does your function is called.
If you're using a version of jQuery older than 1.7 use .delegate() instead of .on(). If you're using a version older than 1.4.2 use .live().
Alternatively, move the $("#inconbutt").click(...) to within the if statement where you append the element.
Rather than appending and removing the whole table every time the checkbox is clicked I'd suggest including it in your code all the time but showing and hiding it.
You're trying to bind an event to the element, which does not exist yet.
Try to use $(document).on('click', '#inconbutt', function() { ... });
Use .on method of jquery
$(document).on('click', '.button.clickable', function () {...});
