jquery map ()

Map () passes each element through a function to the current matching collection, generating a new JQuery object that contains the return value.

. Map (Callback (index,domelement))

Because the return value is an array of jQuery encapsulation, use get () to process the returned object to get the underlying array.

The. Map () method is particularly useful for getting or setting the value of an element set.

<p></p>
<form>
<input type= "text" name= "name" value= "John"/>
<input type= "text" name= "password" value= "password"/>
<input type= "text" name= "url" value= "http://w3school.com.cn/"/>
</form>

<script>
$ ("P"). Append ($ ("input"). Map (function () {
return $ (this). Val ();
}). Get (). Join (","));

</script>

John, password, http://w3school.com.cn/.
