In many cases, the text box has default text, which is usually the text of the prompt class, when you click on the text box to clear the writing text, the following is a brief introduction to how to achieve this effect. The code is as follows:
<!DOCTYPE HTML><HTML><Head><MetaCharSet= "Utf-8"> <title>JavaScript convenience Form</title><Scripttype= "Text/javascript">functionTxtfocus (EL) {if(El.defaultvalue==el.value) {El.value= "'; El.style.color= 'Red'; }}functionTxtblur (EL) {if(El.value== "') {El.value=El.defaultvalue; El.style.color= '#000'; }}</Script><Body><inputtype= "text"style= "color: #666;"onfocus= "Txtfocus (this)"onblur= "Txtblur (this)"value= ' Please enter a predetermined person '></Body></HTML>
