JQuery validation for string value

Question

how do I check if a field has a string value tht contains letters 'abc' containing in it using Jquery ??

I need to check a field that contains a string value, if the field contains the characters 'abc' I need to disable few fields. Please let me know how I can validate in jquery??

Answer 1

if($("#myInput").val() == "abc") {
   $("#myOtherInput").attr("disabled","disabled");
}

Answer 2

One way to go is like:

$('#text_id').keyup(function(){
   if (this.value === 'abc'){
       // disable other fields
   }
});

Or with vanilla javascript:

var el = document.getElementById('text_id');
el.onkeyup = function(){
   if (this.value === 'abc'){
       // disable other fields
   }
};

Where text_id is supposed to be the id of the element you want to check for.

Answer 3

YOu dont need JQuery. do something like this

var s = "foo";
alert(s.indexOf("oo") != -1);

it'll tell you if the variable s contains the text "oo" or not.

Answer 4

if($(":input[value*='abc']").length > 0) {
    // Disable fields
}

This will find you any input field that contains (written somewhere in the field value) abc, though obviously replace ":input" with whatever applies in your case.

Answer 5

var inputString = $('#inputfield').val(); //get value from field
if ((inputString.indexOf("abc") != -1) == true) {
   //disable fields here...
}
