我是 JavaScript 的新手，我不明白为什么这行不通。我的 friend 说尝试使用 .click 或 .select 来测试对选项的点击，但它们都不起作用。
我的 html:
<body>
<form>General
<hr>Full Name:
<br>
<input Type="text" name="name">
<br>Gender:
<br>
<input type="radio" Name="gender" value="Male">Male
<input Type="radio" name="gender" value="female">Female
<br>Birthday:
<br>
<input type="text" name="bday" placeholder="mm/dd/yy">
<br>Email Adress:
<br>
<input type="text" name="email">
<br>PayPal address:
<br>
<input type="text" name="PayPal" placeholder="for when we start paying staff">
<br>Short Biography:
<br>
<textarea rows="4" cols="50"></textarea>
<br>
<br>Apply:
<hr>Username:
<br>
<input type="text" name="nick" placeholder="Your Ingame Name">
<br>What Rank Are You Applying For:
<br>
<select>
<option id="Dev" value="Developer">Developer</option>
<option id="Headadmin" value="HeadAdmin">Head Admin</option>
<option id="Headmod" value="HeadMod">Head Modetator</option>
<option id="Headbuilder" value="HeadBuilder">Head Builder</option>
<option id="admin" value="Admin">Admin</option>
<option id="mod" value="Moderator">Moderator</option>
<option id="builder" value="Builder">Builder</option>
</select>
<br>Why do WE want you (Rank you picked above):
<br>
<textarea rows="4" cols="50"></textarea>
<br>How Many Hours Can You Be On a day:
<br>
<input type="text" name="day">
<br>how many days can you be on a week:
<br>
<input type="text" name="week">
<br>have you been staff before?
<br>
<select>
<option value="yes">yes
<option value="no">no</select>
<br>Test:
<hr>
<div id="DevTest">Devtest</div>
<div id="admintest">admin test</div>
<div id="modtest">mod test</div>
<div id="HAtest">head admin test</div>
<div id="HMtest">head mod test</div>
<div id="HBtest">headbuilder test</div>
<div id="buildertest">buildertest</div>
<br>
<hr>
<textarea readonly rows="5" cols="30">Staff Contract: ---------------- 1. As a staff member, YOU, are represent the "Piggalot Gaming Network" both online and offline. this means; A. If WE, The "Piggalot Gaming Network" Community,</textarea>
<hr>
<input type="checkbox" value="test" required>by clicking this you agree to the staff contract
<br>
<input type="reset">
<input type="submit" value="Send Application">
</form>
我的 JavaScript:
$(document).ready(function(){
$("#Dev").Click(function(){
$("#DevTest").show();
$("#HAtest").hide();
$("#HMtest").hide();
$("#HBtest").hide();
$("#admintest").hide();
$("#modtest").hide();
$("#buildertest").hide();
});
$("#Headadmin").Click(function(){
$("#HAtest").show();
$("#DevTest").hide();
$("#HMtest").hide();
$("#HBtest").hide();
$("#admintest").hide();
$("#modtest").hide();
$("#buildertest").hide();
});
});
这是它的 fiddle 的链接:http://jsfiddle.net/a2nw2sus/1/
最佳答案
<option> 那样不行。收听 change 在 <select> 相反:
$('#id_for_your_select').change(function () {
var selected_value = $(this).val();
switch (selected_value) {
case 'Developer': {
// do something
break;
}
case 'HeadAdmin': {
// do something else
break;
}
}
});
在http://jsfiddle.net/a2nw2sus/2/我修复了拼写错误( click() 与 Click() )，你看:它在 Chrome 中不起作用。在 Firefox 中它可以工作，但您不能认为这是理所当然的!
