Question

I have a simple jquery function as

function sendValue(str){
    $.post("test.php",{ sendValue: str },
    function(data){
        $('#display').html(data.returnValue);
    }, "json");
}

I want to replace space within the string. I thought I can do this by adding

str.replace(" ", "+");

to the second line of the function. But it did not work. I know very basic of javascript. How to replace ” ” with “+” in the string before posting data to test.php?

Answer 1

Try str.replace(/\s/g , "+") instead. (/\s/ is the regex escape for whitespace).

Also are you trying to encode the string as a URL? You could use encodeURIComponent(str) which is a built in javascript method.
