Question

Which of the following methods removes all the spaces before and after an entry in a text box?

a) text()
b) select()
c) val()
d) trim()

Answer 1

Option D is answer. The trim() method is used to remove all spaces before and after an entry in a text box, leaving spaces within the text content untouched.

Step-by-step explanation:

The method that removes all the spaces before and after an entry in a text box is trim(). This function is used in many programming languages, including JavaScript, to clean up input strings. It only removes whitespace from the start and end of the string, not the spaces in between words or characters within the string itself. For example, if a user enters ' hello world! ' into a text box, using the trim() function will result in 'hello world!' without the leading or trailing spaces.

The method that removes all the spaces before and after an entry in a text box is the trim() method. This method is commonly used in programming languages like JavaScript.

For example, if you have a text box with the input value ' Hello World ', calling the trim() method on this input would remove all the spaces before and after the entry, resulting in 'Hello World'.
