Removing 0s from comma seperated value

[dweb]

hey all

 

i have a html form and my input field looks like;

<input id="fieldx" value="1,0,23,0,99">

the value changes each time, but that gives you an example

 

As you'll see, I have 0's in the input field

 

Inside a function, what i want to do is run the following

var elm = document.getElementById('fieldx').value;

then strip any 0's from that input field, and output the new value using

document.form.fieldx.value = stripped_zeros;

so the output would look like

<input id="fieldx" value="1,23,99">

can anyone help?

 

thanks

use javascript replace function

var elm = document.getElementById('fieldx').value;
elm.replace("0","");

after replacing "0" from string it will give output as "1,,23,,99", now replace ",," to blank

elm.replace(",,","");

try this

[Psycho]

var elm = document.getElementById('fieldx').value + ',';
elm = elmAry.replace('0,', '');
elm = elmAry.substr(0, elmAry.length-1)

@Pravin, the problem with the process you proposed is that if the first value was a 0, then it would leave a comma at the beginning of the string.

Thanks, I tried that and ended up with

function do_something()
{
var elm = document.getElementById('fieldx').value;
elm.replace("0","");
elm.replace(",,","");
document.form.fieldx.value = elm;
}

but that didn't seem to work, any idea why?

 

thanks

And what did it do? Any errors? Whya re you referencing the field by the ID at the beginning and then through the form object at the end? Try

//Pass the field ID to the function

function do_something(fieldID)

{

    var fieldObj = document.getElementById(fieldID);

    var elm = fieldObj.value + ',';

    elm = elmAry.replace('0,', '');

    elm = elmAry.substr(0, elmAry.length-1)

    fieldObj.value = elm;

}


//usage

do_something('fieldx')

This works ..

str.replace(/0,|,0$/g, "")

It just doesn't do anything, no errors, just dead, but i'll try your code above

 

Question, do I do the following

document.form.form_product_box_array2.value = fieldObj.value;

or do I use

document.form.form_product_box_array2.value = elm;

thanks

@dweb, the function given by Psycho should work now

 

@Psycho, thanks for noticing the issue of "0" at first and last position

nice one, that's pretty sweet. is there a way to make sure the value ends with a comma? and if not, add one on?

That removes the value and comma that goes with it.  But I did make one mistake.  That will replace like "50,23" and leave "523".

 

Try this.

 

str.replace(/^0,|,0(,)|,0$/g, '$1')
