See if Input Has Spaces with jQuery

Question

I\'m trying to write a function that reads a inputs value, and determines if a space has been used in it\'s creation. I\'m not trying to trim anything -- just see if it woul

Answer 1

Use val and indexOf :

var hasSpace = $('#myInputId').val().indexOf(' ')>=0;

If you want to test other types of "spaces" (for example a tabulation), you might use a regex :

var hasSpace = /\s/g.test($('#myInputId').val());

Demonstration

Answer 2

Use contains for include space:

var value = $('#myInputId').val();
if(value.contains(' ')){
   console.log("has space");
}

Or you can find with these ascII code &nbsp and \xA0

if(value.contains(' ')){
   console.log("has space");
}
