Currently, my goal is to update the color of a span tag only if its value is 0. I attempted to achieve this with the following code:
$('span.number:contains("0")').css('color', '#C1C1C1');
However, this code also changes the color if the number is 50. Is there a method to alter the color of this tag or class exclusively when it is equal to 0?
Employ the filter() method to specifically filter for exact text matches as using :contains may lead to partial matches being included.
$('span.number').filter(function(){
return $.trim($(this).text()) == '0'
}).css('color', '#C1C1C1');
Instead of using a selector, you can directly check the text content:
$("span.number").text(function (_, text) {
if ("0" === text) {
this.style.color = "#C1C1C1";
}
});
Instead of attempting a one-liner, you can simply verify the value before proceeding.
var numVal = $("span.number").text(),
numSpan = $("span.number");
if (numVal === '0') {
numSpan.css('color', '#c1c1c1');
}
Attempting it with
If the value of $('span.number').html() is equal to '0':
Change the color to '#C1C1C1'.
