We all know that HTML5 's input new attribute has placeholder= "", then this incompatible IE low version we can only write with the script.

First HTML creates a new input

<input type= "text" class= "input" value= "Please enter search content"/>

Then we introduce the corresponding JS library, then use jquery

1 <script src= "Js/jquery-1.8.3.min.js" ></script> 2     <script> 3         $ (". Input"). Bind ( {4             focus:function () {  5                 if (this.value = = This.defaultvalue) {  6                     this.value= "";  7                 }  8             },  9             blur:function () {Ten                 if (this.value = = "") {one                     this.value = This.defaultvalue;         ),     </script>

Simple, so that is OK, then this is the text of input, we want to password password also can display IE low version, we use the method is to use two input, a text default display, a password default hidden, When text gets focus password display, text hidden, no input content loses focus text display, password display, OK, nonsense don't say more, look at the code!

1 <!DOCTYPE HTML>2 <HTMLLang= "en">3 <Head>4     <MetaCharSet= "UTF-8" />5     <title>Password box hint</title>6 </Head>7 <Body>8     9     <inputtype= "text"value= "Login Password"class= "Show" >Ten     <inputtype= "Password"class= "Log_paw"style= "Display:none;"> One      A      -     <Scriptsrc= "Js/jquery-1.8.3.min.js"></Script> -     <Script> the         $('. Show'). Focus (function(){ -             varText_value= $( This). Val (); -             if(Text_value==  This. DefaultValue) { -                 $( This). Hide (); +                 $( This). Next ('Input.log_paw'). Show (). focus (); -             } +         }); A         $('Input.log_paw'). Blur (function() { at             varText_value= $( This). Val (); -             if(Text_value== "') { -                 $( This). Prev ('. Show'). Show (); -                 $( This). Hide (); -             } -         }); in     </Script> - </Body> to </HTML>
