jQuery serivalize不起作用。 给出名字

Question

I want to get serialized string from all my checkboxes. Trying to do it this way.

var companies=$("input.company").serialize();
console.log($("input.company").serialize());
alert(companies);

Here is my html form.

    <div id="listOfCompanies"><h1>Список компаний</h1>
    <input type="checkbox" class="company" name="company" value="Microsoft">Microsoft<br>
<input type="checkbox" class="company" name="company" value="Apple">Apple<br>
<input type="checkbox" class="company" name="company" value="Ubisoft">Ubisoft<br>
<input type="checkbox" class="company" name="company" value="sony">sony<br><input type="checkbox" class="company" name="company" value="agilient_technology">agilient_technology<br>
<input type="checkbox" class="company" name="company" value="marvel">marvel<br>
<input type="checkbox" class="company" name="company" value="blizzard">blizzard<br>
<input type="checkbox" class="company" name="company" value="ibm">ibm<br>
</div>

Both console and alert give empty string. Any suggestions?

Unchecked checkboxes aren't included by the browser, which makes sense really because they have a boolean state -- they're either selected by the user (included) or not selected by the user (not included).

alert($("input.company").prop('checked', true).serialize());
