I have an input field:
<input type="hidden" name="url" id="url">
I want this input in form load to have as value the current url, I did it with jquery and it works.
$(document).ready(function () {
$('#url').val(window.location);
});
But how can I simplify it without jquery, since with window.location we can get current URL value, can I do something like this even that this doesn't work:
<input type="hidden" name="url" id="url" value=window.location>
You cannot put JS code in the value attribute, and input elements have no onload attribute you could use (not that that would be very good practice anyway). A pure JS alternative would be to put a <script> tag just before the </body> containing just this:
document.getElementById('url').value = window.location;
All that being said, if you are using jQuery in your site anyway I see no reason not to keep using your original solution within the document.ready event handler.

Is it possible to send anchor tag value through a form?
Some Value
MY application/ use for this is to be used in a web form, in which the options are listed in a ul li a format, rather than a select option format.
Is there any workaround to this, without using select option format? JS or jQuery solutions preferred.
edit: I've found this answer, but it involves ajax. Is there a pure JS/ jQuery method possible?
I think you may consider to use <input type="hidden">.
<form>
Some Value
<input type="hidden" name="link" value="Some Value"/>
</form>
With jQuery-
jQuery(document).ready(function($) {
var current_url = window.location.href;
var hidden_value = "<input type='hidden' name='url' value='"+current_url+"'>";
$(YourFormSelector).append(hidden_value);
});
Just started working in Dreamweaver recently. I was wondering if when you are working with external javascript files, do you have to pass in html elements or can the js file see their id? For example;
<body>
<script src="client.js"></script>
<input type="submit" name="submit" id="submit" onclick="getValue()" value="Submit"></td>
And then in the client.js file
function getValue() {
"use strict";
document.getElementById(submit).value = document.getElementById(otherelement).value;
}
This isn't working in the first place and I understand that there are other errors, but mainly - can the client.js file see and use getElementById(submit) and getElementById(otherelement)?
I would suggest shying away from using inline JavaScript elements, and doing things differently. I'd suggest using addEventListener() to bind events from JavaScript.
So, remove the onclick attribute, and just do:
<input type="submit" name="submit" id="submit" value="Submit">
We will be adding the event in JavaScript. For this to work, the script needs to be ran after the page (DOM) is loaded. You can use window.onload = function(){} to do this or you can load the script at the end of the page (before </body>).
Anyway, in your JavaScript, you want to use:
document.getElementById("submit").addEventListener('click', function(event){
// NOTE: You are clicking a submit button. After this function runs,
// then the form will be submitted. If you want to *stop* that, you can
// use the following:
// event.preventDefault();
// In here `this` will be the element that was clicked, the submit button
this.value = document.getElementById('otherelement').value;
});
document.getElementById( id ) takes id param as string
Use
document.getElementById("otherelement");
document.getElementById("submit");
also remove the </td> as there is no <tr> in your code
If you don't use quotes to wrap your strings, javascript will try to find variables named submit or otherelement. Try adding quotes like that :
function getValue() {
"use strict";
document.getElementById("submit").value = document.getElementById("otherelement").value;
}
If you have an HTML element with an id attribute, The JS engine automatically converts it to a variable..
e.g.
<input type="submit" name="submit" id="submit" onclick="getValue()" value="Submit"></td>
equals to the var submit in your JS code (considering you load your JS file when the DOM is fully rendered).
In every HTML page an element id is unique and that's why it is converted to a variable and wll not be overwritten until you decide so.
I was wondering if when you are working with external javascript
files, do you have to pass in html elements or can the js file see
their id
Yes you can see the ID:
function whoAmI(e) {
document.getElementById('output').textContent = e.target.id;
}
<button id='Hiii' onclick='whoAmI(event)'>Check ID</button>
<p id='output'></p>
I have a 'parent' page that is using the following bit of code to pull in a form from a different page on the same domain. There are reasons why I can't just place the form directly on the 'parent'.
<script type="text/javascript">
jQuery("#ai_temp_profile_edit").load(
"https://example.com/form/ #profile-edit-form",
function() {}
).hide().fadeIn(1000);
</script>
The form that is pulled in looks like this:
<form action="https://example.com/form/" method="post" id="profile-edit-form" class="standard-form base" target="hiddenFrame">
<label for="field_1">Name</label>
<input id="field_1" name="field_1" type="text" value="Joey-Jojo Jr. Shabadoo">
<input type="submit" name="profile-group-edit-submit" id="profile-group-edit-submit" value="Save Changes " />
<input type="hidden" name="field_ids" id="field_ids" value="1" />
<input type="hidden" id="_wpnonce" name="_wpnonce" value="a62f8d5fec" />
<input type="hidden" name="_wp_http_referer" value="/form/" />
</form>
When 'submit' is clicked, https://example.com/form/ is opened in a hidden iframe and the user name gets properly saved. This all works well.
I would like the user name on the currently loaded 'parent' page to update via jquery, so that the user has some immediate visual feedback that the name change has taken place.
My approach has been to try and take the value out of the 'field_1' input when 'submit' has been clicked, and pass that variable onto a div in the parent page with an id of 'display_name'.
$(document).ready(function(){
function nameUpdate(){
$("#profile-group-edit-submit").click(function () {
var updateName = $("#field_1").val();
$("#display_name").text(updateName);
});
}
nameUpdate();
});
I've also tried adding window.parent.
before the the #display_name selector section and it didn't change anything.
I've used this approach on another button/div combo on the same page and it works, the difference is that that particular button is in an iframe, not loaded by jquery. So I'm guessing my problem is related to that fact.
I've googled around, but have run out of ideas of how to phrase my question, what to look for, etc...
Any help would be greatly appreciated. Thanks!
Edit: For clarity, the div w/ id #display_name won't update.
Use jquery to handle the form submission.
$(document).ready(function(){
$('#profile-edit-form').submit(function(){
var updateName = $("#field_1").val();
$("#display_name").text(updateName);
});
});
EDIT:
Due to your loading the form dynamically you need to bind the submit function after the load. So...
$(document).ready(function () {
var formLoaded = function () {
$('#profile-edit-form').submit(function () {
var updateName = $("#field_1").val();
$("#display_name").text(updateName);
});
};
$("#ai_temp_profile_edit").load(
"https://example.com/form/ #profile-edit-form",
formLoaded
).hide().fadeIn(1000);
});
If I am understanding it correctly, your problem is "display_name" field is not getting updated with the latest value.
If this is the problem then can you try below thing?
Instead of
$("#display_name").text(updateName);
try using-
$("#display_name").val(updateName);
As per the documentation on jQuery site Val() works well with form Elements whereas text won't.

let me start by saying it may look simple but im finding it extremely difficult.
ive made a search script that uses PHP and to fetch a result would look like this
search.php?term=alice&submit=Submit
Standard stuff.. problem is, i use an SPI with AJAX and PHP so my results would have to load dynamically into a div, whilst still keeping the hash value, as not to lose the page the user had visited previous to searching.
jQuery.history.js is the plugin i use for back button support, which requires links to be like such:
Home Page
this would load 'home.html' into a div named pageContent. as far as i know theres no way to call php files unless you develop a little hack, which i have,
here is my JavaScript/jQuery for my search form:
<script language="JavaScript">
$(document).ready(function() {
// bind form using ajaxForm
$('#search1').ajaxForm({
// target identifies the element(s) to update with the server response
target: '#pageContent',
// success identifies the function to invoke when the server response
success: function() {
$('#pageContent');
var hash = '#search.php?term='+($('#query').val()+'&submit=Submit').replace(/ /g, '+');
var stripped = hash.replace(/(<([^>]+)>)/ig,"");
update(window.location.hash = stripped);
}
});
});
</script>
Heres the form:
<form id="search1" action="search.php" method="post">
<input id="query" type="text" name="term" />
<input type="submit" name="submit" value="Submit" />
</form>
My problem is this:
ive tried this.form.reset(); this: Resetting a multi-stage form with jQuery , yet none of this works. please help me if you know a way of doing this..
$('#query').val(DefaultValue);
with this u can set your value to whatever you want, like blank: '';
EDIT: For some reason if I change the input into an , the submit code works fine. Ok, this works, I'll just style the a tag to look like an input tag in css.
I am using a jQuery function to submit a form when a certain button is pressed, however this seems to have no effect on the form.
My code is as follows:
HTML:
<form id="loginForm" action="" method="POST">
<input class="loginInput" type="hidden" name="action" value="login">
<input id="step1a" class="loginInput" type="text" name="username">
<input id="step2a" class="loginInput" type="password" name="password" style="display:none;">
<input id="step1b" class="loginSubmit" onclick="loginProceed();" type="button" name="submit" value="Proceed" title="Proceed" />
<input id="step2b" class="loginSubmit" onclick="submitlogin();" type="button" value="Validate" title="Validate" style="display:none;" />
</form>
Javascript:
function submitlogin()
{
$("#loginForm").submit();
}
function loginProceed()
{
$("#step1a").fadeOut("slow",function(){
$("#step2a").fadeIn("slow", function(){
$("#step2a").focus();
});
});
$("#step1b").fadeOut("slow",function(){
$("#step2b").fadeIn("slow");
});
$("#step1c").fadeOut("slow",function(){
$("#step2c").fadeIn("slow");
});
}
However, when I press the button, absolutely nothing occurs.
PS. This function may seem meaningless since I can just use a input type="submit" but I originally intended this to have some more functionality, I stripped the function to its bare bones for testing purposes.
Try to use another name for input with name="submit". Without this it works fine for me.
You need to specify one form.
$("#loginForm").submit();
EDIT: Additional information added to question. You appear to be calling the wrong function. The submit button that is not display:none calls loginProceed() not submitlogin().
Also, if the functions are defined within jQuery's ready() function, they will be out of scope unless you define them as global.
Live example: http://jsfiddle.net/eSeuH/
Updated example: http://jsfiddle.net/eSeuH/2/
If the code you noted in the comment runs before the DOM is loaded, it will not work. You need to ensure that it does not run until the DOM has loaded (or at least the element it references has loaded).
$(document).ready(function() {
$("#loginForm").submit(function() { alert("clicked"); });
});
Additionally, your action attribute in your form tag is empty. What do you expect to happen when the form is submitted?
Try look in to Firefox debug console. Maybe you have errors in javascripts???
Because even if action is empty, all works.
For some reason if I change the input into an , the submit code works fine. Ok, this works, I'll just style the a tag to look like an input tag in css.
There's no jquery 'submit' method (not for ajax, at least): http://api.jquery.com/category/ajax/
You probably want to invoke form's submit method:
$("#loginForm")[0].submit();
Remember, jquery selector always returns array.
edit
'submit' will actually bind handler to submit event, not submit form:
