What could be the issue causing my code to not properly update CSS properties?

My jQueryMobile project involves overriding the CSS for listviews with the following code:

li{
height:90px !important;
border-style: 0px !important;
border-width: 0px 5px 2px 0px !important;
-moz-border-image: url('images/FA-iPhone_my-goals_READY-(2)_02.png') 0 5 2 0 stretch     !important;
-webkit-border-image: url('images/FA-iPhone_my-goals_READY-(2)_02.png') 0 5 2 0 stretch     !important;
-o-border-image: url('images/FA-iPhone_my-goals_READY-(2)_02.png') 0 5 2 0 stretch     !important;
border-image: url('images/FA-iPhone_my-goals_READY-(2)_02.png') 0 5 2 0 fill stretch !important;}

All is good so far. However, I have a challenge with implementing an image button within each listview. To tackle this issue, I followed the instructions provided at:

In order to change the properties and values of the li selector when clicking on the image button, I used the method below. The id #four1 represents the page, while #selectbtn refers to the image button labeled as "select". Upon clicking, the intention is to alter the CSS properties as shown below.

<script>
$('#four1').live('pagecreate', function(e){
$("#selectbtn").click(function(e) {
$('li').css({'height': '90px !important'});
$('li').css({'border-style': '0px !important'});
$('li').css({'border-width': '0px 5px 2px 0px !important'});
$('li').css({'-moz-border-image':url('+images/goalsel_02.png+ !important')'});
$('li').css({'-webkit-border-image':url('+images/goalsel_02.png+ !important')'});
$('li').css({'-o-border-image':url('+images/goalsel_02.png+')' !important});
$('li').css({'border-image': 'url('+images/goalsel_02.png+')' !important});

    });
});
</script>

Answer №1

To correctly set CSS properties in jQuery, follow this format using JSON:

$(element).css({ "property1" : "value1", "property2" : "value2" });

If you only need to add one property, use this simpler method:

$(element).css("property", "value");

Remember, the single property method does not require JSON formatting.

Answer №2

Ensure proper assignment of properties is done.

$(element).css("property", "value"); // when assigning a single property

Alternatively,

$(element).css({ "property1" : "value1", "property2" : "value2" }); // for more than one property, ensure correct quotation marks are used

Be attentive to your use of quotes.

For example:

$(element).css({ "background-image" : "url('path_to_image') !important" });

Answer №3

When selecting your element, make sure to only do it once to avoid redundancy. Consider consolidating all CSS styles into a single function as demonstrated in the solutions provided.

If you need to apply multiple functions to a specific element, utilize chaining for efficiency (refer to: ). This approach prevents jQuery from repeatedly searching for the same element with each function applied.
