Question

i am trying to write a validator which could validate the bunch of commas like (,,,,,,,,,)
if single comma(,) is there then its ok .
here is my code

function test() {

    var iChars = ",,";
    for (var i = 0; i < document.mform.show_time1.value.length; i++) {
        if (iChars.indexOf(document.mform.show_time1.value.charAt(i)) != -1) {
            alert("The box has special characters. \nThese are not allowed.\n");
            return false;
        }
    }
}       

but the above script is also validating (,) that i don’t want .

Any idea how to do that ??

Answer 1

are you trying to find out string which has multipe ,,,, in it

For Example

string = " I have ,,,, this many commas ?"

then your test() function should be something like this.

function test(){

    if(string.indexOf(",,") > -1 ){
        alert("The box has special characters. \nThese are not allowed.\n");
    }

}

I hope this helps, or please clarify the question once again.
