Truncate leading zeros of a string in Javascript

Question

Hi all,

I have a textbox in Javascript. When I enter '0000.00' in the textbox, I want to know how to convert that to only having one leading zero, such as '0.00'.

Please anybody help me in this regard.

Thanks in advance..

Answer 1

Try this:

<input type="text" onblur="this.value=this.value.replace(/^0+(?=\d\.)/, '')">

Answer 2

var value= document.getElementById("theTextBoxInQuestion").value;
var number= parseFloat(value).toFixed(2);

Answer 3

It sounds like you just want to remove leading zeros unless there's only one left ("0" for an integer or "0.xxx" for a float, where x can be anything).

How about this for a first cut?

while (s.charAt(0) == '0') {
    if (s.length == 1) { break };
    if (s.charAt(1) == '.') { break };
    s = s.substr(1,s.length-1)
}
