js的作用是什么 1、能够嵌入动态文本于HTML页面。2、对浏览器事件做出响应。3、读写HTML元素。4、在数据被提交到服务器 之前验证数据。5、检测访客的浏览器信息。6、控制cookies,包括创建和修改等。7、基于Node.js技术进行服务器端编程。
1、使用Vue.js实现双向表单数据绑定,例子

#VueFormSub.js(实现双向绑定主要代码)
//实现取值
var VueFormSub = function(formid){
this.$form = ($("#" + formid).length !=0)?$("#" + formid):$("."+formid);
var models = $("*[v-model != '']", this.$form);
var vueData = {};
$.each(models,function(idx,dom){
var key = $(dom).attr("name");
if (undefined != key){
var dValue = $(dom).val();
$(dom).val(dValue);
var beanName = key.split("_");
if(beanName.length < 2){
vueData[beanName] = dValue;
vueData[beanName] = $("input[type='radio'][name='"+key+"']:checked").val();
}else{
if(vueData[beanName[0]] == undefined){
vueData[beanName[0]] = {};
}else{
if($(dom).attr("type") == "radio"){
var tempVal = $("input[type='radio'][name='"+key+"']:checked").val();
vueData[beanName[0]][beanName[1]] = tempVal;
}else{
vueData[beanName[0]][beanName[1]]=dValue;
}
}
}
}
});
return vueData;
};
#初始化Vue表单数据(可以只传入initDate数据源,formid需要绑定的dom)
VueFormSub.initVue = function(initDate,formid,httpMethod, url, params){
if(initDate instanceof Object){
/*if(initDate.length !=0){}*/
var initJson = VueFormSub.ObjConvert(initDate);
new Vue({
el : ($("#"+formid).length != 0)?'#'+formid:'.'+formid,
data : initJson
});
}else{
if (httpMethod != "get" && params && typeof (params) == "object"){
params = JSON.stringify(params);
}
if(params!= null){
params.rs = Math.random();
}else{
params = {'rs':Math.random()};
}
$.ajax({
type: httpMethod,
url: "/cxh" + url,
data: params,
cache:false,
async: true,
contentType: 'application/json',
dataType: 'json',
success: function (returnData) {
if(returnData.length != 0){
var vueDate = VueFormSub.ObjConvert(returnData);
new Vue({
el:($("#"+formid).length != 0)?'#'+formid:'.'+formid,
data : vueDate
});
}
}
});
}
};
#对需要绑定的对象进行解析成Vue支持的格式
VueFormSub.ObjConvert = function(dataObj){
var json = {};
$.each(dataObj,function(id,param){
if(param instanceof Object){
$.each(param, function(rid,rparam){
if(rparam instanceof Object){
json[id] = VueFormSub.ObjConvert(param);
}else{
json[id+"_"+rid] = rparam;
}
});
}else{
json[id]=param;
}
});
return json;
}; #使用实例
