    text
    copied!<p>I have various questions about setTimeout: - In my code, I clean timeouts with <code>clearTimeout(content.idTimeout)</code> for a particular idTiemout, but how clear all timeouts? I have the next model:</p> <pre><code>var ContentModel = Backbone.Model.extend({ URL: "http://localhost/example.php", requestType: "POST", dataType: "json", data: "", //Set the value outside the model idTimeout: "", initialize: function() { _.bindAll(this); }, startSend: function (Data) { }, reply: function (Data) { var dataJson = eval(Data); console.log(dataJson); this.idTimeout = setTimeout(this.ajaxRequest(),4000); }, problems: function (Data) { }, ajaxRequest: function () { $.ajax({ async:true, type: this.requestType, dataType: this.dataType, url: this.URL, data: this.data, beforeSend:this.startSend, success: this.reply, timeout:4000, error:this.problems }); } </code></pre> <p>And clean timeouts in the view (fragment):</p> <pre><code>initialize: function() { _.bindAll(this); this.model = new ContentCollection(); this.model.on("add", this.contentAdded); this.model.on("remove", this.removeContent); }, contentAdded: function(content) { //run it when add a model if (content.view == null) { var template_name = 'cam'; content.view = new ContentView({model: content,template: $.trim($("[template='"+ template_name +"'] div").html() || "Template not found!")}); $("div.camBox").empty(); content.ajaxRequest(); this.$el.find(".content").find("div.camBox").append(content.view.render().el); } }, removeContent: function(content) { if (content.view != null) { content.view.remove(); } clearTimeout(content.idTimeout); content.clear(); //Clear the properties of the model } </code></pre> <p>- How clean a timeout when the focus is in other window and resume it when returns? Maybe with focus method. The next code </p> <pre><code>$('html').focus(function() { clearTimeout(content.idTimeout); }); </code></pre> <p>in contentAdded does not work.</p> <p>Edit: </p> <p>http://stackoverflow.com/questions/14258596/way-to-stop-the-running-of-a-javascript-web-application-when-the-focus-is-on-oth</p>
