jQuery得到 <select>值而不是所选值<option>值

Question

In the above example the console logs a value of 1 which is the currently selected option. How can you log the <select> tag's value of 2?

 $(document).ready(function() { console.log($('.mySelect').val()); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <select class="mySelect" value="2"> <option value="1" selected>Choice 1</option> <option value="2">Choice 2</option> <option value="3">Choice 3</option> </select> 

Answer 1

This is not valid HTML syntax.

Use data attributes like data-someattr for values you want to pass.

Answer 2

这将为您工作。

console.log( $('.mySelect[value=2]').val() );
