Issue with .css() function failing to apply width attribute

My goal is to shift the width of a div as specific images load in my application. I have tried reading the div's current width, adding 128 to it, and then using the .css() function to update the div's new width. However, I have encountered an issue where the .css() function only updates the width on the last image that is loaded, rather than updating it as each image loads. I am unsure why this is happening. Here is the code I am using:

document.getElementById('back').onload = function(){
    var width = $("#LoadingBar").css("width").replace(/[^-\d\.]/g, '');
    width = parseInt(width);
    var newwidth = width + increment;
    newwidth = newwidth +"px";
    $('#LoadingBar').animate({width:newwidth},"fast");
    if(width == 1280) {
        //I display another div once all the images have loaded            
        $("#everything").show();
     }
}

Do you have any suggestions on what may be causing this issue?

Answer №1

Utilize the jquery width method to adjust the widths of elements on your webpage.

CSS should be used for more intricate properties of your HTML elements.

$("#LoadingBar").css("width")

Can also be written as:

$("#LoadingBar").width()

You also have the option to set the width:

$("#LoadingBar").width(MyWidthValue);

Answer №2

Try utilizing `jQuery` to retrieve the numerical value of the width by using `var width = $("#LoadingBar").width()` instead of relying on `css width`. You can then increase the value and add units accordingly.

Answer №3

Follow these steps to adjust the width

$(<custom element>).width(function (a, w) {return w+=128});

If you want to animate the change, use this code snippet

$(<custom element>).animate({width:"+=128"},'fast');
