问题描述
我正在使用jquery的ui对话框表单代码.本质上，如果您单击按钮，则会弹出一个弹出窗口，并要求用户输入名称电子邮件和密码.我希望发生这种情况，但我不想单击该按钮，我什至希望在用户单击表中的td时发生这种情况.
这是jquery ui随附的代码
I am using jquery''s ui dialog form code. Essentially if you click a button a pop up pops up and asks the user to enter name email and password. I want this to happen but i don''t want to click the button, I want this even to happen when a user clicks a td in a table.
This is the code jquery ui comes with

<div id="dialog-form" title="Create new user">
<p class="validateTips">All form fields are required.</p>
<form>
<fieldset>
<label for="name">name</label>
<input type="text" name="name" id="name" class="text ui-widget-content ui-corner-all" />
<label for="email">email</label>
<input type="text" name="email" id="email" value="" class="text ui-widget-content ui-corner-all" />
<label for="description">description</label>
<input type="description" name="description" id="description" value="" class="text ui-widget-content ui-corner-all" />
</fieldset>
</form>
</div>
<button id="create-user">Create new user</button>
</div><!-- End demo -->
</body>
</html>
现在，我尝试将id = create-user添加到td，以使它看起来像这样，而不是< button id ="create-user">创建新用户</button>.我还尝试将button:event更改为td:indead，但是什么也没有.我不知道还要做什么?
Now I tried to add the id=create-user to the td so it looks like this instead of the <button id="create-user">Create new user</button>. I also tried to change the button: event to td: indead, but nothing. I am not sure what else to really do?
