[jQuery] Re: Need to validate Multiple email IDs with Comma Seprated

[Kuo Yang]

With pleasure.

My English is not so good,so I paste the code directly:


//copied from http://www.webtoolkit.info/javascript-trim.html
function trim(str, chars) {
    return ltrim(rtrim(str, chars), chars);
}
function ltrim(str, chars) {
    chars = chars || "\\s";
    return str.replace(new RegExp("^[" + chars + "]+", "g"), "");
}
function rtrim(str, chars) {
    chars = chars || "\\s";
    return str.replace(new RegExp("[" + chars + "]+$", "g"), "");
}

//I modified the regex.
function validateEmail(field) {
    //var regex=/\b[a-z0-9._%+...@[a-z0-9.-]+\.[a-z]{2,4}\b/i;
    var regex=/^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
    return (regex.test(trim(field))) ? true : false;
}
function validateMultipleEmailsCommaSeparated(value) {
    var result = value.split(",");

    alert(result);
    for(var i = 0;i < result.length;i++)
    if(!validateEmail(result[i]))
            return false;
    return true;
}
