Enable and disable of text box through a checkboxWe may need to enable or disable a text box based on the input of the user by using disabled property of the element. For example we have some choices for the visitor and one of the options is Others. Once the visitor select the others options then ( only ) one text box will be enabled to allow the visitor to fill the details.
We have used the body onload command to keep the text area disabled while the page is loading.
