Remove spaces in a Javascript variable

rated 0 times [ 198] [ 5] / answers: 1 / hits: 20070 / 12 Years ago, wed, november 28, 2012, 12:00:00

I'm using AJAX to retrieve data from MYSQL database through PHP.

However, if there is no result found, the variable still has two spaces. I found the problem using alert(data.length);. The result is 2, which means there are two spaces.

How can I remove these spaces so that if there is no result, I could display a message using if(data == ''){}?

Thank you!

This is called string trimming. And here is one option for that in pure JavaScript:

var len = data.replace(/s/g, ).length;

However, in modern browsers there is a string trim() function for that:

var len = data.trim().length;
