I was trying to add text into field with id #shouttext, but i need to trim value from onclick event which is just after (' and also delete ') symbols.
So if i have
<img src="images/smilies/at.png" alt="" title="" class="smilie smilie_9 smilie_pointer" onclick="MyBBEditor.insertText(':at:');">
I want to get
:at:
and add it to input with #shouttext id. Below is my code, which doesn't work - and i think its blocked by defined onclick value, which i was trying to remove.
<script type="text/javascript">
$( document ).ready(function() {
$('.smilie').click(function()
{
var s1,s1;
s1=attr("onclick");
s1=s1.replace('MyBBEditor.insertText(\'', '');
s2=s1.replace('\')', '');
$('.smilie').attr('onclick','').unbind('click')
$('#shouttext').val($('#shouttext').val()+s2);
})
});
</script>
Thanks for any help in advance!
you could try also:
var str = $(".smilie").attr("onclick").split("'")[1];
to get the :at: try it here: fiddle
now you can use it here:
$('.smilie').unbind("click");
$('.smilie').click(function() {
var str = $(".smilie").attr("onclick").split("'")[1];
$('#shouttext').val($('#shouttext').val() + "" + str);
});
or how #eg_dac says, you can override the click event with $.on()
instead of unbinding it in the click, you can do
$(".smilie").attr("onclick", ""); // clear the already declared attribute.
$(".smilie").on("click", function(){
$('#shouttext').val($('#shouttext').val()+s2);
});
Example found here http://jsfiddle.net/meougz1L/
$("img").attr("onclick","");
$("img").on("click", function(){
alert("click event overridden");
});

What I've tried:
function addAttribute(){
document.getElementById('myid')...
};
window.onload = addAttribute;
How can I add add the attribute to my element with id="myid" ?
document.getElementById('telheaderid').yourattribute = "your_value";
For instance
document.getElementById('telheaderid').value = "your_value";
Using jQuery:
$('#telheaderid').attr('value', 'your_value');
EDIT:
Focus is the event that fires up when an element get focused or for instance when we click on the textarea it highlights thats the time.
Using jQuery:
$('#telheaderid').focus(function() {
$(this).val('');
// run any code when the textarea get focused
});
Using plain javascript:
document.getElementById('telheaderid').addEventListener('focus', function() {
this.value = "";
});
Use this:
document.getElementById('telheaderid').setAttribute('class','YourAttribute')
The W3C standard way:
function functionAddAttribute(){
document.getElementById('telheaderid').setAttribute('attributeName', 'attributeValue');
};
window.onload = functionAddAttribute;
for IE:
function functionAddAttribute(){
document.getElementById('telheaderid').attributeName = 'attributeValue';
};
window.onload = functionAddAttribute;
Enjoy your code!
Now, If I hit the button, it clears all in the input field, and it automatically inputs "#marry" to it.
But, I don't want it to be cleared:(
What if I want to add "#marry" to the end of the strings that already exists in the input field?
How can I customize my javascript part?
Input field
<textarea class="box text_area" cols="10" id="input" name="comment[body]"></textarea>
button
<a href="#topic" id="username" value="#marry”><span class='btn'>reply</span></a>
javascript
$(document).on('click', 'a#username', function() {
$(".box#input").val($(this).attr('value'));
}
val() has a callback with the arguments index and value, you can use that to easily add something to the value.
$(".box#input").val(function(_, val) {
return this.value + 'some extra string';
});
$(document).on('click', 'a#username', function() {
var self = this;
$(".box#input").val(function(_, val) {
return val + self.value;
});
});
First of all adeneo's answer is good and you should read it. Here is an alternative solution that does not use jQuery:
I assume that both these elements are a part of a form. Let's say for instance the form has an ID of "post". We can access it using document.forms and then its fields as such:
var input = document.forms.post["comment[body]"];
Now, we can add to its value whenever the button is clicked. First select username with getElementById or querySelector and then add the event:
username.addEventListener("click", function(ev){
input.value += ev.target.value;
});
Or with jQuery (this also delegates if the element is not in the DOM yet):
$(document).on('click', 'a#username', function() {
input.value += this.value;
});
It might be desirable to append an extra space between the current text and the username.
append #marry at the end of text area. you can use bellow code its working fine.
$(document).on('click', 'a#username', function () {
var txtvalue = $(".box#input").val();
$(".box#input").val(txtvalue + $(this).attr('value'));
});

I want to hook events with the .on() method. The problem is I don't know how to get the object reference of the element on which the event take place. Maybe it's a midunderstanding of how the method really works... but I hope you can help.
Here's what I want to do:
When a file is selected, I want the path to be displayed in a div
<div class="wrapper">
<input type="file" class="finput" />
<div class="fpath">No file!</div>
</div>
Here's my script
$(document).ready(function() {
$this = $(this);
$this.on("change", ".finput", {}, function() {
var path = $(this).val()
$(this).parents().children(".fpath").html(path.split("\\").pop());
});
});
Something like that but that way it doesn't work.
Like this
$(document).ready(function() {
$('.finput').on("change", function() {
var path = $(this).val()
$(this).parents().children(".fpath").html(path.split("\\").pop());
});
});
Do you need to use on()? I'm not sure what you are trying to do exactly.
$("#wrapper").on("change", ".finput", function(event){
var path = $(this).val()
$(this).parents().children(".fpath").html(path.split("\\").pop());
});
I haven't tested your code, but you need to attach the on() to the wrapper.
Can you just use change()?
$('.finput').change(function() {
var path = $(this).val()
$(this).parents().children(".fpath").html(path.split("\\").pop());
});
This should help. If you want to see when a file input changes, bind the event to it
$("input[type='file']").on("change", function(e){
var path = $(this).val();
})
Try:
$(document).ready(function() {
$('body').on('change','input.finput', function() {
var path = $(this).val()
$(this).parent().children(".fpath").html(path.split("\\").pop());
});
});
$(document).on("change", ".finput", function() {
$(".fpath").html(this.value.split("\\").pop());
});
This is a delegated event handler, meaning the .finput element has been inserted dynamically so we need to delegate the listening to a parent element.
If the .finput element is not inserted with Ajax and is present on page load, you should use something like this instead:
$(".finput").on("change", function() {
$(".fpath").html(this.value.split("\\").pop());
});
Need to identify each of these 'a' tag in div and bind an onclick event.I have binded the same.I need to append some text below the clicked 'a' tag.But when i tried with my code it binds to all the 'a' tag in the div.How can i specify the 'a' tag which i have clicked.I can make changes to the content in div using jquery.can't modify the content in 'a' tag.
<div class="people_rt_link2">
2011<br><br>
2008<br><br>
</div>
$(document).ready(function() {
var timesClicked = 0;
$('.people_rt_link2 a').bind('click', function() {
jQuery.post("<?php bloginfo('template_directory'); ?>/test.php", data, function(response) {
alert('Got this from the server: ' + response);
//this response should to binded to the clicked a tag
//$(this).after('<div>'+response+'</div>');
});
timesClicked++;
if (timesClicked >= 1) {
$(this).unbind();
}
});
});
Use this to refer to the clicked <a>. Example using jQuery:
$('div.people_rt_link2 a').click(function(){
$(this).unbind('click');
var that = this;
$.post('somepage.php', function(data){
$(that).after(data);
});
return false;
});
Example
Let me know if that's not exactly what you were trying to achieve.
Theres lots of ways to specify the a tag you want to append text too.. first child.. first of type.. but mostly you just append an id to the tag and let javascript handle it..
$("people_rt_link2 a.YourClass").bind("click", function({do stuff}));
http://www.w3schools.com/tags/tag_a.asp
try something like this:
$("people_rt_link2 a").bind("click", foo(<!--Put here all your code you want to be executed -->));
$(document).ready(function () {
$("href").attr('href', 'title');
});
$('a[href$=.jpg]').each(function () {
var imageSrc = $(this).attr('href');
var img = $('<img />').attr('src', imageSrc).css('max-width', '300px').css('max-height', '200px').css('marginBottom', '10px').css('marginTop', '10px').attr('rel', 'lightbox');
$(this).replaceWith(img);
});
});
This is the jQuery code I have at the moment, which I want to change all links' href to the same as their title, before then embedding them in the page. Yet with the changing href to title bit in the code, it stops working. I'm new to Javascript so am definitely doing something wrong, just not sure what yet! Any help much appreciated!
Thank you guys
EDIT
This is the html that I want to change:
<p class="entry-content">Some interesting contenthttp://example.com/index.php/attachment/11</p>
You are changing it wrong, you are trying to select href elements instead of a.
This fix should do it:
$("a[title]").each(function() {
$(this).attr('href',$(this).attr('title'));
});
It will select all a elements with title and set the href with this value.
Here's a much more efficient way.
Since you're just replacing the <a> elements, there's really no need to change its href. Just select the <a> elements that end with jpg/jpeg, and use that attribute directly.
Example: http://jsfiddle.net/5ZBVf/4/
$(document).ready(function() {
$("a[title$=.jpg],[title$=.jpeg]").replaceWith(function() {
return $('<img />', {src:this.title, rel:'lightbox'})
.css({maxWidth: 300,maxHeight: 200,marginBottom: 10,marginTop: 10});
});
});
Your .each() is outside the .ready() function.
You can accomplish the href change easily like this:
$(document).ready(function () {
$("a").attr('href', function() { return this.title; });
});
The .attr() method will accept a function where the return value is the new value of (in this case) href.
So the whole thing could look like this:
Example: http://jsfiddle.net/5ZBVf/3/
$(document).ready(function() {
$("a[title]").attr('href', function() { return this.title; })
.filter('[href$=.jpg],[href$=.jpeg]')
.replaceWith(function() {
return $('<img />', {src:this.href, rel:'lightbox'})
.css({maxWidth: 300,maxHeight: 200,marginBottom: 10,marginTop: 10});
});
});
This line:
$("href").attr('href','title');
Is finding all href elements and replacing their href attr with the string 'title'. Since there is no such thing as an href element, Try this instead:
// for every anchor element on the page, replace it's href attribute with it's title attribute
$('a').each(function() {
$(this).attr('href', $(this).attr('title');
});
Check this out: http://jsfiddle.net/TbMzD/ Seems to do what you want.
Note: $(document).ready() is commented because of jsfiddle, you actually need it in your code.
Try:
$("a").each(function () {
var $this = $(this);
$this.attr('href', $this.attr('title'));
});
