我想删除与主模板一致的最终创建视图 我确实尝试了以下实现,但没有成功
// main-template.html
<div id=""project>
<div class="main-template">
<div id="view1"></div>
<div class="foldable-block">
<div id="view2"></div>
<div id="view3"></div>

您可以从评论中看到的问题位于
view1.js
(this.$el) // []
从我的js控制台,它可以工作:
$("#view1") // <div>….</div>
将子视图附着到在需要时不存在的图元。类似这样的事情可能是朝着正确方向迈出的一步: mainView.js
define([
"js/views/view1",
"js/views/view2",
"js/views/view3",
"text!templates/main-template.html"
], function (View1, View2, View3, mainTemaplte) {
var MainView = Backbone.View.extend({
initialize: function ()
{
this.render();
},
render: function ()
{
// render from template and assign this.el to the root of the element
// e.g #project
var html=Mustache.render(mainTemaplte);
this.setElement( $(html) );
// create each view with its el set to the correct descendant
this.view1 = new View1( _.extend( {el:this.$("#view1")} , this.options) );
this.view2 = new View2( _.extend( {el:this.$("#view2")} , this.options) );
this.view3 = new View3( _.extend( {el:this.$("#view3")} , this.options) );
}
});
return MainView;
});
define([… ], function (..) {
var View1 = Backbone.View.extend({
initialize: function () {
console.log(this.$el);
}
});
return View1;
});
view1.js
define([
"js/views/view1",
"js/views/view2",
"js/views/view3",
"text!templates/main-template.html"
], function (View1, View2, View3, mainTemaplte) {
var MainView = Backbone.View.extend({
initialize: function ()
{
this.render();
},
render: function ()
{
// render from template and assign this.el to the root of the element
// e.g #project
var html=Mustache.render(mainTemaplte);
this.setElement( $(html) );
// create each view with its el set to the correct descendant
this.view1 = new View1( _.extend( {el:this.$("#view1")} , this.options) );
this.view2 = new View2( _.extend( {el:this.$("#view2")} , this.options) );
this.view3 = new View3( _.extend( {el:this.$("#view3")} , this.options) );
}
});
return MainView;
});
define([… ], function (..) {
var View1 = Backbone.View.extend({

您可以使用以下内容重新创建视图
require(["js/views/mainView"], function(MainView) {
var view=new MainView();
console.log(view.$el);
//attach the view to the DOM
$("body").append(view.$el);
});
ti工作得很好。只有一个问题
this.$el
已在view1.js中定义,当我在view1.js
中调用render时,this.$el
已正确填充,但未附加到文档正文。我怎么做这个?我确实发布了更多关于view1.js的代码。@下划线666您的view1渲染应该可以正常工作,并且可以在主视图中更新#view1。如果我理解正确,mainview是应该附加到DOM的。我修改了上一个代码块以反映这一点。还是我遗漏了什么?
require(["js/views/mainView"], function(MainView) {
var view=new MainView();
console.log(view.$el);
//attach the view to the DOM
$("body").append(view.$el);
});
