Question

Well like the title says, how can i check it?
i have started something like this:

    for (var i = 0; i < elm.val().length; i++) {
        if (elmVal.charAt(i) !== '') {
            //do something
        }
    }

For example:

if the string is: “g g g” OR “gg g ” it should be illegal.

You can split the string and check word one by one

var str = "hi how r you";
str_split = str.split(" ");
$.each(str_split,function(){
    console.log(this.length);
})
