You can use $.trim
$.trim(yourstring)
which will allow for cross browser compatibility
In your case it would be
var x = $.trim($("#clueOneInput").find('input[type=text]').val());
Вопрос
var $one = $('#oneClueShow');
var x = $("#clueOneInput").find('input[type=text]').val();
if(x == 'D R' || x == 'd r'|| x == 'D r'|| x == 'd R'|| x == 'd'|| x == 'r' || x == 'd R' || x == 'T A')
Above is a snippet of java/ I have. What it does is takes an input -- then checks for a match. The bug I'm looking to resolve is if there are spaces after or before it isn't recognized.
For example within the input someone can type 'D R' no problem. If a space is added like so 'D R ' then it no longer recognizes the input.
Is there something I can do to affect the input to ensure no space before/after prior to button click? I've been looking into replace, but can't seem to get it going.

Use the trim()
method
Example:
var str = " Hello World! ";
alert(str.trim());
This will output :
Hello World!
var str = " Hello World! ";
alert(str.trim());
You may use the trim() method.
Do this for cross-browser:
var x = $("#clueOneInput").find('input[type=text]').val().replace(/^\s+|\s+$/g,"");
You can do a check before-hand:
if (!String.prototype.trim) {
String.prototype.trim = function () {
return this.toString().replace(/^\s+|\s+$/g, '');
};
}
Will enable .trim
in non-supported browsers. And then, you can use it like:
var x = $("#clueOneInput").find('input[type=text]').val().trim();
With the benefit that you can use this .trim
method at many other places in the code too.
You should always use $.trim() while comparing the string. You can use $.trim() like:
if($.trim(x) == 'D R' || $.trim(x) == 'd r'|| $.trim(x) == 'D r'|| $.trim(x) == 'd R'|| $.trim(x) == 'd'|| $.trim(x) == 'r' || $.trim(x) == 'd R' || $.trim(x) == 'T A')
