我有一个页面,其中有两个元素,一个输入文本框和一个按钮
现在我在文本框上有一个模糊事件处理程序,它首先显示一个 jquery ui 模式窗口,然后发出一个 ajax 请求,一旦请求完成,我将关闭对话框。另外我在按钮上有一个点击事件处理程序(它也做某事)。
现在,当我在文本框中键入内容并直接单击按钮时,模糊和单击事件处理程序都应该触发,但它只会触发模糊并且由于 jquery ui 模态对话框而导致单击事件被阻止(当我删除对话框时,两个事件被解雇了)
这是示例代码
// the topic/subscription hash
var pubsub_cache = {};
$.publish = function(/* String */topic, /* Array? */args){
// summary:
// Publish some data on a named topic.
// topic: String
// The channel to publish on
// args: Array?
// The data to publish. Each array item is converted into an ordered
// arguments on the subscribed functions.
//
// example:
// Publish stuff on '/some/topic'. Anything subscribed will be called
// with a function signature like: function(a,b,c){ ... }
//
// | $.publish("/some/topic", ["a","b","c"]);
pubsub_cache[topic] && $.each(pubsub_cache[topic], function(){
this.apply($, args || []);
});
};
$.subscribe = function(/* String */topic, /* Function */callback){
// summary:
// Register a callback on a named topic.
// topic: String
// The channel to subscribe to
// callback: Function
// The handler event. Anytime something is $.publish'ed on a
// subscribed channel, the callback will be called with the
// published array as ordered arguments.
//
// returns: Array
// A handle which can be used to unsubscribe this particular subscription.
//
// example:
// | $.subscribe("/some/topic", function(a, b, c){ /* handle data */ });
//
if(!pubsub_cache[topic]){
pubsub_cache[topic] = [];
}
pubsub_cache[topic].push(callback);
return [topic, callback]; // Array
};
$.unsubscribe = function(/* Array */handle){
// summary:
// Disconnect a subscribed function for a topic.
// handle: Array
// The return value from a $.subscribe call.
// example:
// | var handle = $.subscribe("/something", function(){});
// | $.unsubscribe(handle);
var t = handle[0];
pubsub_cache[t] && $.each(pubsub_cache[t], function(idx){
if(this == handle[1]){
pubsub_cache[t].splice(idx, 1);
}
});
};
var $loaderDialog = $('<div>The dummy dialog</div>')
.dialog({
autoOpen:false,
modal:true
});
$('.validate').on('change', function(){
$loaderDialog.dialog('open');
setTimeout(function(){
$.publish('validation-done');
},3000)
});
$.subscribe('validation-done', function(){
$loaderDialog.dialog('close');
console.log('validation done');
});
$('#btn').on('click', function(){
alert('clicked');
});
