我通过点击按钮
在我的Backbone.view中创建动态弹出窗口var Section = Backbone.View.extend({
className: 'sqs-frontend-overlay-editor-widget-section',
events:{
'click .sqs--section--control__edit': 'Section_control'
},
initialize: function(){
},
render: function(){
this.$el.append(_.template(_section).apply(this.options));
return this.$el;
},
Section_control: function(){
var me = this;
require(['View/Popup/Section_control'], function(_Section_control){
var sec = new _Section_control({popup: popup, sec: me.options.section});
var popup = new Popup({content: sec.render()});
});
}
});
return Section;
在创建的动态弹出窗口中,我有带触发器的按钮:
events:{
'click .module-invert-mode': 'invert'
},
invert: function(e){
console.log('hello');
if(this.options.sec.hasClass('.module-invert')) {
console.log('yse');
}
this.options.sec.toggleClass('module-invert');
this.options.sec.trigger('invertChange');
},
和按钮invertChange
触发:
el.on("invertChange", function(e){
var section = el.parents('section');
var index = section.index();
var model = collection.at(index);
model.set(Helper.sectionToObj(section),{doReload: true})
});
查看我在{doReload: true}
中调用的invertChange
函数:
change: function(model, options){
me = this;
if( model._changing && options.doReload ) {
$.ajax({
url: 'wp-admin/admin-ajax.php',
type: 'post',
data: {
action: 'getShortcode',
shortcode: model.attributes.shortcode
},
success: function (data) {
//var section = $(data);
me.$el.find('section:eq(' + model.collection.indexOf(model) + ')').replaceWith(data);
me.add( model, model.collection );
//me.collection.add({shortcode: model.attributes.shortcode}, {at: section.index()});
}
});
}
},
问题是当我创建动态弹出窗口并单击带有invertChange
触发器的按钮时,ajax只能工作一次,当我再次单击弹出窗口中的按钮时,ajax不起作用(下一个ajax请求有效)只有关闭并再次创建动态弹出窗口)。如何在不经常关闭和打开动态弹出窗口的情况下调用ajax?
答案 0 :(得分:1)
您有代码覆盖子视图的问题
me.$el.find('section:eq(' + model.collection.indexOf(model) + ')').replaceWith(data);
此侦听器无法处理事件
el.on("invertChange", function(e){
因为你的代码
this.options.sec.trigger('invertChange');
不会在正确的视图上触发事件,它在replaceWith()
作为解决方案,您需要解析data
对象并将每个更改本地应用于元素
类似这样的事情
$(data).find("* [attr]").each(function(i, el) {
var $el = $(el),
attr = $el.attr("attr"),
$parent = me.$el.find('section:eq(' + model.collection.indexOf(model) + ')');
if ($el.is("div, span")) {
$parent.find('[attr=' + attr + ']').html($el.html());
} else if ($el.is("img")) {
$parent.find('[attr=' + attr + ']').attr("src", $el.attr("src"));
} else if ($el.is("a")) {
$parent.find('[attr=' + attr + ']').attr("href", $el.attr("href"));
} else if (attr == "image_back_one") {
$parent.find('[attr=' + attr + ']').attr("style", $el.attr("style"));
} else {
console.log($el);
}
});
