What is the best way to implement CSS properties dynamically in real-time?

Hey there, I’m working with some HTML code here

 <div id="div1"></div>

I’m dynamically loading content onto this div and adjusting its width in the "success" function based on the contents

Here’s the jQuery code snippet I’m using

The data variable is an array returned from PHP and its length is 30

 success: function (data) {
        var data1 = data;
        var w2 = (data1.length) * 100;
        $("#div1").css({'width' : w2 + 'px'});
        alert($("#div").width());

Unfortunately, when I alert the width, I receive a NULL value and div1 remains at the default width

jquery css ajax

Adjust it in this way

      $("#element1").css('height', h2);

Next, display the height of "#element1" and not "#element".. like this

      alert($("#element1").height());

Here is the complete process:

success: function (response) {
    var responseData = response;
    var h2 = (responseData.length) * 50;
    $("#element1").css('height', h2);
    alert($("#element1").height());
}

Below is the updated function with improved readability after removing data1:

function adjustWidth(data) {
    var newWidth = data.length * 100;
    $("#div1").css('width', newWidth);
    alert($("#div").width());
}

Your CSS was applied to a different selector than the one used in the alert message. Additionally, the alert is missing a closing parenthesis.

 $("#box1").css('height', h2+'px');
alert($("#box2").height());
