Suggested October 2023 Guide To Examples Of Jquery Ui Trim() Method

Definition of jQuery trim

The jQuery UI trim() method is used to remove the whitespace from both ends of a string. The jQuery UI trim() method is a built-in method. Sometimes we need to trim a string that removes the whitespace from the start and end of the string, but the whitespaces in the middle of the string are preserved, so jQuery provides the trim() method for this purpose. The trim() method is a string method, so when we call this method we will pass a string parameter.

The syntax of the JQuery trim() method.

Next, we write the HTML code to understand the jQuery UI trim() method more clearly with the following example, where the trim() method is used to remove the spaces from both sides of the string, as below.

Example #1

Code:

pre { display : block; border : 2px solid green; color : red; padding : 6px; margin : 12px; } $(document).ready(function(){ var str= “ Hello, how are you “; $(“.original”).html(str); }); var str= ” Hello, how are you “; var trimstr = jQuery.trim( str ); $(“.trimmed”).html(trimstr); }); });

An output of the above code is:

As in the above program the string ” Hello, how are you ” is store in the str variable, if we see this string contain the whitespaces in the front and end of the string. So to remove these spaces the trim() method is used which is accepted the ” Hello, how are you ” string and returned the output as “Hello, how are you”, which is printing as we can see in the output.

Next we write the html code to understand the jQuery UI trim() method more clearly with the following example, where the trim() method is used to remove the spaces from the left side of the string by calling the trim() method on the string only, as below –

Example #2

pre { display : block; border : 2px solid green; color : red; padding : 6px; margin : 12px; } $(document).ready(function(){ var str= “ Hello, how are you”; $(“.original”).html(str); }); var str = ” Hello, how are you”; str = str.trim( str ); $(“.trimmed”).html(str); }); });

An output of the above code is:

As in the above program the string ” Hello, how are you” is store in the str variable, if we see this string contain the whitespace or spaces only in the front of the string. To remove this space the trim() method is used which is accepted the ” Hello, how are you” string and returned the output as “Hello, how are you”, so the trim() method is not removed anything from the end of the string because it does not contain any space at the end as we can see in the output.

To remove this space the trim() method is used which is accepted the ” Hello, how are you” string and returned the output as “Hello, how are you”.
