I'm working on a .net website that validates an input and if it fails adds an inline style
"display:inline;"
Im trying to use jQuery to see this style and add a class to the respective input field.
if(!!$('span.errorp').length ){
alert('hi');
}
the above is what im currently using to ensure i can target the correct tag which works,
I guess i need something similar too...
if(!!$('span.errorp').display:inline ){
alert('hi');
}
Try the following
if ($('span.errorp').css('display') === 'inline') {
...
}
You can use something like:
$('span.errorp').css('display', 'inline');
It's not necessary to check for length. If there are no matches, nothing happens.
if($('span.errorp[style=display:inline]')) {
// do stuff
}

I've added some custom elements to be included with my WooCommerce account page to be seen with the order history. Unfortunately the page is setup with tabs to only display the information pertaining to the active tab.
I'm not very familiar with jquery, but I thought it would be simple enough to use Jquery to hide the divs I added when the order history has a display of none.
I added the following script to my theme's main.js file:
$(document).ready(function(){
var display = $('.my_account_orders');
if(display.css("display") == "none") {
$('.paging-nav').css("display","none");
}
});
When the class .my_account_orders has a display of none it should change the div I added (.paging-nav) to have a display of none. But it just doesn't work.
Is there something wrong with this script or do I need to do something special to initiate it? Since it's in my theme's main.js file and I used $(document).ready(function() I figured it would just load with the page.
Any help with this would be greatly appreciated.
Instead of using:
var display = $('.my_account_orders');
Implement it into the if statement like this:
if($('.my_account_orders').css("display") == "none") {
Because originally it is trying to find a variable called $display, so it would return a syntax error of undefined.
You've got an errant $ in your if statement. This should work instead:
$(document).ready(function(){
var display = $('.my_account_orders');
if(display.css("display") == "none") {
$('.paging-nav').css("display","none");
}
});
Also keep in mind that your var display is only going to match the first element that has a class of my_account_orders, so if there are multiple elements with that class, and they don't all have the same display, you could get unexpected results.
Try this:
$(document).ready(function(){
var display = $('.my_account_orders');
if(display.css("display") == "none") {
$('.paging-nav').css("display","none");
}
});
I believe it's a very lame way to check for a css property such as display to determine if an element is hidden or not. With jquery, you can make use of :hidden selector which determines whether an element is hidden and return a bool value.
$(document).ready(function(){
if($('.my_account_orders').eq(0).is(":hidden")) // eq(0) is optional - it basically targets the 1st occurring element with class 'my_account_orders'
{
$('.paging-nav').css("display","none");
}
});

How can i hide a the text under class named amount using javascript or php?
<span class="amount">$0.00</span>
I tried the following but no luck
<script language="javascript">
$(".amount:has(a:contains('$0.00'))").hide();
</script>
Assuming jQuery based on code in original question.
Your original script was close. All you really need is:
$('.amount:contains($0.00)').hide()
Documentation: https://api.jquery.com/contains-selector/
Bonus
If you can't use jQuery, here's how to do it the old fashioned way.
Array.prototype.forEach.call(document.getElementsByClassName('amount'), function (e) {
if (e.innerText == '$0.00') {
e.style.display = 'none';
}
})
Setting styles is JavaScript isn't too clean, so the better thing to do would be to set a class, with corresponding CSS to hide elements matching that class. For example e.classList.add('hidden'); and .hidden { display: none; }
Documentation: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach (IE 9+)
https://developer.mozilla.org/en-US/docs/Web/API/Element/classList (IE 10+)
Try something like:
<script>
// Assign object
var AmtObj = $(".amount");
// Get contents
var Amount = AmtObj.html();
// If equals '$0.00', hide
if(Amount == '$0.00') {
AmtObj.hide();
}
</script>
try with this code:
var item = $(".amount");
if(item.html() === "$0.00"){
item.hide();
}
Its a lot of trouble for what you want especially if you wanna extract the numbers without the formatting.
If you control the data add a data-value to your attribute and put the raw number their such as <span class="amount" data-value='0.00'>$0.00</span> and then select it and hide it.
$(document).ready(function(){
$(".amount:contains('$0.00')").hide();
});
I want to make Textarea Disable (Grayed out) in my JS Method
function myfun(status){
if(status=='Yes'){
$('input[id$="txtareaID"]').attr('disabled','disabled');
}
The above code is not working for this.
You should use prop instead of attr:
$('input[id$="txtareaID"]').prop('disabled', true);
jQuery docs
If your selector is correct, than you need only to change attr to prop:
function myfun(status){
if(status === 'Yes'){ // more suitable for comparing
$('input[id$="txtareaID"]').prop('disabled',true);
}
}

Disable/enable an input with jQuery?
Considering textarea as
<textarea id='txt'>Something</textarea>
Using jQuery, you can achieve like this
$("#txt").attr('disabled', true);
Using plain javascript
document.getElementById("txt").disabled=true;
Your problem is with CSS not JS. As far I can tell your code is working, but there's no way of changing this specific style. You could try workarounds: Change Font Color For Disabled Input
<textarea> is what you should be looking for not the <input> tag with id = textareaid.
$('input[id$="txtareaID"]').attr('disabled','disabled');
change the above code to the below one and see the magic by clicking the link at the bottom.
$('textarea[id$="txtareaID"]').attr('disabled','disabled');
http://jsfiddle.net/5s9ge7d6/1/
none of the below answers worked.
Then I found something amazing trick which solved my problem ---
Here it is --- JUST REMOVE "input" word from that line in if block -
WORKED CODE :
function myfun(status){
if(status=='Yes'){
$('[id$="txtareaID"]').attr('disabled','disabled');
}
Previous CODE :
function myfun(status){
if(status=='Yes'){
$('input[id$="txtareaID"]').attr('disabled','disabled');
$('input[id$="txtareaID"]').prop('disabled',true); //Didn't worked either
}
I'm new to jquery and I'm trying to turn off a specific css sheet when a specific page loads. This is the code that I've been using and I'm not sure that it is correct.
if(location.pathname=="/mycart") >= 0){
$('link[rel=stylesheet][src~="/media/css/responsive.css"]').remove();
}
The problem might be that path name check... also, instead of removing, try disabling the stylesheet:
if (location.pathname.indexOf('/mycart') >= 0) {
$('link[href*="/media/css/responsive.css"]').prop('disable', true);
}
Edit: The ~= selector looks for a space deliminated word, so use the *= selector instead.
Update (full code)
<script>
$(function () {
if (location.pathname.indexOf('/mycart') >= 0) {
$('link[href*="/media/css/responsive.css"]').prop('disable', true);
}
});
</script>
Instead of complicating things with on the fly style-sheets "canceling" why don't you simply create a wrapper class around objects that change on your page and define two sets of selectors that apply in case the wrapper does or does not have a specific class.
Lets say this is your HTML code.
<div class="my_cart">
<!-- Lots of shiny elements defined inside your cart... -->
</div>
Now you simply add two sets of stylesheets depending on how you actually want to style your cart in different situations.
.my_cart input {
...
}
.my_cart p {
...
}
/* The following two selectors will be applied to .my_cart ONLY if it also has the .disabled class assigned to it. */
.my_cart.disabled input {
...
}
.my_cart.disabled p {
...
}
Now all you have to do is following.
$(document).ready(function(){
if(location.pathname == "/mycart"){
$('.my_cart').addClass('.disabled');
}
});
Simple as that.
I have a link to hide/display some text:
<a href="javascript:void(0);" id="toggle_status_history">show/hide history<a/>
The corresponding JavaScript looks like this:
$(document).ready(function() {
$('#toggle_status_history').click(function() {
if ($('#status_history').is(":hidden")) {
$('#status_history').slideDown("fast");
} else {
$('#status_history').slideUp("fast");
}
});
It works great, but I'd like to toggle the hyperlink text as well. What do I need to do to modify the 'show/hide history' to show either 'hide history' (if it's currently displayed) or 'show history' if it's currently hidden? Something like this..?
$(document).ready(function() {
$('#toggle_status_history').click(function() {
if ($('#status_history').is(":hidden")) {
$('#status_history').slideDown("fast");
// SOMETHING HERE TO SET TEXT TO 'HIDE HISTORY'
} else {
$('#status_history').slideUp("fast");
// SOMETHING HERE TO SET TEXT TO 'SHOW HISTORY'
}
});
Disclaimer: I have less than an hour of experience with JQuery (and I haven't used JavaScript since the late-90s) - I'm just trying to modify a code sample for my site. I've looked at the API for the toggle() and replaceWith() functions but am not getting it to work. Googling and RTFM'ing hasn't helped me so far.
$('#status_history').text("Whatever you want it to say");
Have a look at the jQuery Documentation. They have a very good documentation which explains everything, with examples. For example, the .text(str); function is underneath manipulation.
$('#toggle_status_history').text("Show history");
$('#status_history').text("Hide/Show History"); is what you need.
The better way of doing such things is using toggle method provided by jQuery, it accepts a list of functions which will be looped on each click. So that you don't need to do is(':hidden')
$('#status_history').val("bla bla bla..");
try this...
fn.val() is getting the value of input, select or textarea's value or text ;)
fn.val(newValue) is setting new values ;)
$(document).ready(function() {
$('#toggle_status_history').click(function() {
$('#status_history').toggle('slow')
$("#toggle_status_history").text(($("#toggle_status_history").text()=='show')?'hide':'show');
}
});
