Jquery Validate if field contains a comma

Question

I have been looking around but can't find a way to do this. I really like the jquery validate script and I was wondering if there was a way to check to see if a field contains a comma and not validate if there is no comma.

Answer 1

您可以按此处所述使用.inArray()方法。应拆分字符串，然后可以使用此方法： var found = $.inArray(',', categories) if(found == -1) alert("Error!")

Answer 2

not familiar with jquery validate but str.indexOf returns the position where something appears in a string, -1 means it doesnt. check a string for a comma like this :

if (yourString.indexOf(',') > -1) {
    validate();
}

Answer 3

If you are referring to the jquery validate plugin:

$.validator.addMethod(
    "regex",
    function(value, element, regexp) {
        var re = new RegExp(regexp);
        return this.optional(element) || re.test(value);
    },
    "Please check your input."
);

$("#input").rules("add", { regex: "," })
