Before submitting a form, JQuery modifies the original submitted value. jqueryfont

When I was working on a company project today, I encountered a problem:

We hope that when searching for the second-level column, we can determine whether the user has added the unique Keywords of this column (for example, "tutorial"), because we are a full-site search. If no keyword is added, there will be a lot of things to be searched out, so we just want to find all the things related to the tutorials in this topic, so we have a little bit of attention, make minor changes to the search keywords. The Code is as follows:

Copy codeThe Code is as follows:
$ ('# Search-form'). submit (function (){
// Retrieve the keyword
$ Keyword = $ ('# keyword ');
 
// Determine whether the keyword "tutorial" is included
If ($ keyword. val (). indexOf ('tutorial ') <0)
{
$ Keyword. val ($ keyword. val () + '');
}
});

You can use this code. When we search for a CSS tutorial, the program will determine that the package does not contain any, and will not splice the word "tutorial" With keyword, when we search for CSS, We splice it into a "CSS tutorial" to search.

OK. I hope I can help you.
