一. 准备工作
1. 点击此下载相关文件，并把文件放到 ims 工程对应的文件夹下
二. 相关文件介绍
1. login.jsp：系统主界面

</table>
</form>
</div> <script type="text/javascript" src="content/js/jquery/jquery-1.8.1.min.js"></script>

$(function () {
ko.applyBindings(new viewModel());
});

2. login.js：绑定登录界面的功能按钮
var viewModel = function () {
var self = this;
this.form = {
userCode: ko.observable(),
password: ko.observable(),
remember: ko.observable(false),
city: null
};
this.message = ko.observable();
this.loginClick = function (form) {
if(utils.isEmpty(self.form.password()))// 浏览器记住密码 不执行knockout监听
self.form.password($("#password").val());
if(utils.isEmpty(self.form.userCode()))
self.form.userCode($("#userCode").val());
$.ajax({
type: "POST",
url: rootPath+"/sys/login.do",
data: ko.toJSON(self.form),
dataType: "json",
contentType: "application/json",
success: function (d) {
if (d.status == 'success') {
self.message("登陆成功正在跳转，请稍候...");
window.location.href = rootPath+'/';
} else {
self.message(d.message);
}
},
error: function (e) {
self.message("登陆失败");
},
beforeSend: function () {
$(form).find("input").attr("disabled", true);
self.message("正在登陆处理，请稍候...");
},
complete: function () {
$(form).find("input").attr("disabled", false);
}
});
}; this.resetClick = function () {
self.form.userCode("");
self.form.password("");
self.form.remember(false);
}; this.init = function () {
$.getJSON("http://api.map.baidu.com/location/ip?ak=F454f8a5efe5e577997931cc01de3974&callback=?", function (d) {
self.form.city = d.content.address;
});
if (top != window) top.window.location = window.location;
//判断之前是否有设置cookie，如果有，则设置【记住我】选择框
if(com.cookie('userCode')!=null){
self.form.remember(true);
}else{
self.form.remember(false);
} //读取cookie
if(self.form.remember()){
self.form.userCode(com.cookie('userCode'));
self.form.password(com.cookie('password'));
}
}; this.init();
};
三. 效果图
1. 访问：http://localhost:8080/ims/login.do，登录主界面
