Question

jQuery doesn't just insert values; it neatly organizes them in a perfect line

Hey there, I have a bit of a silly question, but I could really use some help!

I'm facing an issue with changing the height of a div using jQuery by adding values. Instead of adding up, they are just lining up one after another. Wondering if anyone else has encountered this problem before?

Here's my code snippet:

jQuery( document ).ready(myfunction);
$(window).resize(myfunction);

function myfunction() {
    var divH = $('.container').css("height");
    divH = divH .replace(/px/g, "");

    var innerH = parseInt(divH) + 130;

    $('.divRight').css("width", innerH);
}

For instance, if the .container height is 100px, the expected output should be 230px (100+130), but instead, it shows 100130.

If you have any insights on why this might be happening, I would greatly appreciate your input!

Thank you in advance!

Answer №1

The problem arises from concatenating string values instead of adding integers. To resolve this issue, it is necessary to convert the height() value to an integer. This can be accomplished by utilizing the parseInt() function:

$(document).ready(updateSize);
$(window).resize(updateSize);

function updateSize() {
    var containerHeight = parseInt($('.container').css("height"), 10);
    var adjustedHeight = containerHeight + 130;
    $('.divRight').css("width", adjustedHeight);
}

To convert a string into a number, you can either add a plus sign before the string or use the functions number() or parseInt().

 var innerH = +divH + 130;  // 230

Convert a string into a number using: Number(divH), parseInt(divH);

ALTERNATIVELY

 var innerH =  130 + divH;  // 230

IMPORTANT: Remember that divH is actually a string, so when added to a number, it will concatenate instead of adding.

Always remember to use parseInt when dealing with numeric strings, as it ensures accuracy. For calculations involving decimals, make sure to use parseFloat.

var containerHeight = parseInt($('.container').css("height"), 10);

Alternatively,

var newHeight = parseInt(containerHeight) + 130;
