How to properly generate exceptions in PHP/Dojo when returning javascript code

由 北城余情 提交于 2019-11-27 08:22:25
问题 I am having difficulty understanding how exceptions are handled when code is fetched dynamically via AJAX and executed via eval . With clientside javascript, it is rather simple, if I have a piece of code such as this var j = 'some string'; j.propA.x++; this will raise an exception because propA , which is of type undefined does not have an x . Furthermore, the exception raised is very easy to understand. Now lets put the above code in a text file, lets call it test.js , and store it on the

Set download path

问题 I have a web application that receives a simple text file, but I need this file to be downloaded to a specific path. Meaning, when the application receives a text file, it will always be downloaded to a specific folder (for example, to C:\MyFolder). If it isn't possible, then I need to copy the file from where user has chosen to my folder. This application is based on JavaScript. 回答1: JavaScript cannot exert any control over my (the visitor's) local filesystem. I remain in complete control of

由 生来就可爱ヽ(ⅴ＜●) 提交于 2019-11-27 07:24:33
问题 I'd like to have a dojo grid which connects to a server url which outputs the following json : {identifier : "id" items : [ { id: "1", name: "John", university : { name: "XXX", address: "YYY" } }].

I tried using the dojox.grid.DataGrid object and creating a gird layout, but do not know how to refer to the nested elments and university.name and university

Does Dojo have an equivalent to jQuery.trigger()?

由 一世执手 提交于 2019-11-27 06:42:56
问题 In jQuery, you can do this: $('#myElement').trigger('change'); How do I do that in Dojo? 回答1: I don't think Dojo has similar functionality, at least as not as far as I know / can find. But you can use code like the following to replicate this functionality: dojo.addOnLoad(function() { var button = dojo.byId("myButton"); dojo.connect(button, "onclick", function() { alert("Clicked!"); }); // IE does things differently if (dojo.isIE) { button.fireEvent("onclick"); } else { // Not IE var event =

How to copy a DOM node with event listeners?

由 ＊爱你＆永不变心＊ 提交于 2019-11-27 04:34:57
I tried node.cloneNode(true); // deep copy It doesn't seem to copy the event listeners that I added using node.addEventListener("click", someFunc); . We use the Dojo library. cloneNode() does not copy event listeners. In fact, there's no way of getting hold of event listeners via the DOM once they've been attached, so your options are: Add all the event listeners manually to your cloned node Refactor your code to use event delegation so that all event handlers are attached to a node that contains both the original and the clone Use a wrapper function around Node.addEventListener() to keep

What is the Dojo equivalent to jQuery .live()?

问题 What is the Dojo equivalent to jQuery .live()? http://api.jquery.com/live/ The only solution I found was to dojo.disconnect the event handlers and re-connect them once a dynamic piece of markup was added to the page. 回答1: usage and demo dojo.query("body").delegate(selector, eventName, fn); code - rewrites the original mixin-like delegate function of dojo dojo.provide("dojox.NodeList.delegate"); dojo.require("dojo.NodeList-traverse"); dojo.extend(dojo.NodeList, { delegate: function ( selector

ajax call in jsf 2.0 (myfaces), the onevent Javascript function in the ajax tag gets called before the rendering is complete

由 北战南征 提交于 2019-11-27 03:25:30
问题 This is my first time asking a question on a forum, since usually my questions have already been asked and answered. I haven't found an answer to this problem that works for me, so here goes: I'm making an Ajax call in JSF 2.0 like this: < f :ajax listener="#{myReferenceController.clearRequiredReferenceNumber}" onevent="resetFocus" execute="@form" render=":resultsForm:ResultsDisplay" /> Everything in the listener works perfectly, and the data is then rendered as expected in the data table

问题 I would like to add a generic dialog with "Ok" and "Cancel" buttons support callback functions. How can I achieve this with a Dojo AMD? For example: myDialog = new Dialog ({ title: "My Dialog", content: "Are you sure, you want to delete the selected Record?", style: "width: 300px", onExecute:function(){ //Callback function console.log("Record Deleted") }, onCancel:function(){ console.log("Event Cancelled") } }); // create a button to clear the cart new Button({ label:"Ok" onClick: myDialog
