The method of removing a string by jquery

In jquery, you can remove a string by replacing a string with an empty one using the replace () method.

Create a new html file, named test.html, to explain how jquery removes a string. Within the p tag, use the input tag to create a string input box. Set the id of the input tag to strinput, which is mainly used to obtain the input object through this id.

Use the button tag to create a button with the name "remove abc string". Bind the onclick click event to the button button, and execute the strfun () function when the button is clicked.

Within the js tag, create the fun () function, within which you get the input object through id (strinput), get the input string using the val () method, and replace the specified string with an empty one using the replace () method, for example, replacing the abc string with an empty string to remove a string. Finally, the processed string is output using the alert () method.

Open the test.html file in the browser, enter the string, click the button to view the result.
