Answer 1

If you're working in HTML 5 with input element, i would suggest you to look at the placeholder attribute, as this is exactly what you are needing for. No javascript needed.

 <input type="text" placeholder="Enter Email Address" />

Answer 2

使用转义符\\

'\\'Enter Email\\''

Answer 3

try this

'\'Text\''

or

"'Text'"

Answer 4

尝试这样的事情，从双引号中删除反斜杠， FIDDLE

<input type="text" onfocus="if(this.value=='Enter Email Address'){this.value='';}" onblur="if(this.value=='')    {this.value='Enter Email Address';}" value="Enter Email Address">
