[英]Why does a button cause my whole web page to reload?
I have a web page I'm working on with jQuery. 我有一个我正在研究jQuery的网页。 I'm getting erratic behavior from some elements on my page: Every time a button, any button, on the page is clicked, the page refreshes.
我从页面上的某些元素中获得了不稳定的行为:每次单击页面上的按钮,任何按钮,页面都会刷新。
The page must somehow be running some code that reloads that page any time a button is clicked. 该页面必须以某种方式运行一些代码,以便在单击按钮时重新加载该页面。
I'm completely stumped trying to figure out where the code is getting bound to the click handler, so I would like to know if it is possible to enumerate, at run-time, a list of handlers attached to a button. 我完全难以找到代码绑定到click处理程序的位置,所以我想知道是否可以在运行时枚举附加到按钮的处理程序列表。
Update: After reading the answers given below, I changed a line in my page:
更新:阅读下面给出的答案后,我在页面中更改了一行:
<button id="btnSaveAndContinue" class="button" tabindex="290">Save and Continue</button>
to this: 对此:
<input type='button' id="btnSaveAndContinue" class="button" tabindex="290" value='Save and Continue' />
This is the default behaviour of a button. 这是按钮的默认行为。 If you want to change it, do something like this:
如果你想改变它,做这样的事情:
$("button selector").click( function(event) {
event.preventDefault();
});
