我只有一个简单的超链接,当我试图添加一个 click()
事件处理程序时,它不起作用。我试过了,.on()、.live()、.delegate()
都没有用。我该怎么做?
我无法做出 fiddle ,因为我不知道为什么我的 bootstrap.min.css 没有包含在外部资源部分中。
请告诉我其他方法。
我的代码:
HTML:
<div class="navbar nav-fixed-top navbar-inverse" style="min-height: 50px; margin-bottom: 0; box-shadow: 0px 2px 5px #222;">
<!-- Creating a fixed to the top navbar with no bottom margin and a nice little shadow and increasing the height -->
<div class="navbar-inner" style="border-radius: 0;min-height: 50px; ">
<!-- Creating the inner content of navbar and increasng it's height aswell to match the parent's height aswell -->
<div class="container-fluid">
<!-- Main header starts -->
<button type="button" class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<!-- Small screen collapseable menu starts --> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span>
<!-- The collapseable menu icon(becuase the three `icon-bar` make an icon :P) -->
</button> <a class="brand" href="#"><img src="img/logo.png"
style="height: 25px;" /> </a>
<!-- adding the logo to the header -->
<div class="nav-collapse collapse pull-right">
<!-- div holding collapseable menu's data -->
<ul class="nav">
<!-- creating a list to be created in the collapseable menu -->
<li><a href="#" id="register_button">Register</a>
</li>
<!-- adding an hyper link to the collapseable menu -->
</ul>
<!-- closing the list -->
</div>
<!-- closing the div holding collapseable menu's data -->
</div>
<!-- closing the main header -->
</div>
<!-- closing inner content holder of navbar div -->
</div>
<!-- closing the fixed to top navbar holder -->
CSS: 使用 bootstrap.min.css
JS:
var registerBtn = $("#register_button"); //storing the hyperlink of register in a variable
var i = 0; //click count
$(registerBtn).on('click', function (e) {
i++;
if (i % 2 === 0) {
$("#register_frm").fadeToggle('fast', function () {
$("#login_frm").fadeToggle('fast');
});
$("#register").text('Register');
} else {
$("#login_frm").fadeToggle('fast', function () {
$("#register_frm").fadeToggle('fast');
});
$("#register").text('Login');
}
});
有什么建议吗?
最佳答案
更改代码:
$(function() {
var registerBtn = $("#register_button"); //storing the hyperlink of reg....
var i = 0; //click count
registerBtn.on('click', function (e) { // since registerBtn is a reference to anchor tag
e.prevenDefault(); // prevent default behaviour of anchor tag
.........
});
});
