  • custom helpers inside each block

    - by Unspecified
    myArray = [{name: "name1", age: 20}, {name: "name2", age:22}]; {{#each person in myArray}} {{#myHelper person}} Do something {{/myHelper}} {{/each}} Handlebars.registerHelper(function(context, options){ if(context.age > 18){ return options.fn(this); }else{ return options.inverse(this); } }) In the above code when I tried to debug my custom helper it shows the context="person" while I want the context to be the person object, what's wrong with my code ? I found a similar question here but did not get it either...

  • AJAX: Problems returning multiple variables

    - by fwaokda
    First off sorry if I'm missing something simple just started working with AJAX today. I have an issue where I'm trying to get information from my database, but different records have different amounts of values. For instance, each record has a "features" column. In the features column I store a string. (ex: Feature1~Feature2~Feature3~Feature4... ) When I'm building the object I take apart the string and store all the features into an array. Some objects can have 1 feature others can have up to whatever. So... how do I return this values back to my ajax function from my php page? Below is my ajax function that I was trying and I'll provide a link with my php file. [ next.php : http://pastebin.com/SY74jV7X ] $("a#next").click(function() { $.ajax({ type : 'POST', url : 'next.php', dataType : 'json', data : { nextID : $("a#next").attr("rel") }, success : function ( data ) { var lastID = $("a#next").attr("rel"); var originID = $("a#next").attr("rev"); if(lastID == 1) { lastID = originID; } else { lastID--; } $("img#spotlight").attr("src",data.spotlightimage); $("div#showcase h1").text(data.title); $("div#showcase h2").text(data.subtitle); $("div#showcase p").text(data.description); $("a#next").attr("rel", lastID); for(var i=0; i < data.size; i++) { $("ul#features").append("<li>").text(data.feature+i).append("</li>"); } /* for(var j=1; j < data.picsize; j++) { $("div.thumbnails ul").append("<li>").text(data.image+j).append("</li>"); } */ }, error : function ( XMLHttpRequest, textStatus, errorThrown) { $("div#showcase h1").text("An error has occured: " + errorThrown); } }); });

  • Ajax response takes time and status is 503

    - by Suresh S
    guys, i have a html page where onclick of a button a ajax request is sent to server , the request calls a jsp page which runs an oracle procedure.The procedure runs the logic and places it in a temp table . once procedure is completed , the values are returned to the client by selecting values from tmp table. as the response is too late . the data is not received at the client side. solution: i tried to run the procedure in a separate thread using a ajax call. when the procedure is completed a global flag is set to indicate that the data is generated. if the response is 500 , a second ajax call invoked by timeout function after 10000 ms . the second call checks the global flag ,if true then reads from table and sends the response. if not again a timeout is set at the client side. this solution is not mature enough. , as the procedure may take long time to respond. please let me know a good solution for this problenm?

  • select2: "text is undefined" when getting json using ajax

    - by user3046715
    I'm having an issue when getting json results back to select2. My json does not return a result that has a "text" field so need to format the result so that select2 accepts "Name". This code works if the text field in the json is set to "text" but in this case, I cannot change the formatting of the json result (code outside my control). $("#e1").select2({ formatNoMatches: function(term) {return term +" does not match any items." }, ajax: { // instead of writing the function to execute the request we use Select2's convenient helper url: "localhost:1111/Items.json", dataType: 'jsonp', cache: true, quietMillis: 200, data: function (term, page) { return { q: term, // search term p: page, s: 15 }; }, results: function (data, page) { // parse the results into the format expected by Select2. var numPages = Math.ceil(data.total / 15); return {results: data.Data, numPages: numPages}; } } }); I have looked into the documentation and found some statements you can put into the results such as text: 'Name', but I am still getting "text is undefined". Thanks for any help.

  • How to implement partial refresh like facebook like/comments?

    - by shillong
    We have java web application. Summary page will display list of rows. For each row, user can vote and add comments. Vote or add comments will commit immediately and refresh total vote number and comments count. We want to refresh current row instead of whole table just like Facebook does. If need, we can show the list of data with form format (iterator List of data) instead of table format. How to implement this feature base on JSF?

  • Real world examples of Ecmascript functions returning a Reference?

    - by Bergi
    Read the EcmaScript specification, section 8.7 The Reference Specification Type: The Reference type is used to explain the behaviour of such operators as delete, typeof, and the assignment operators. […] A Reference is a resolved name binding. Function calls are permitted to return references. This possibility is admitted purely for the sake of host objects. No built-in ECMAScript function defined by this specification returns a reference and there is no provision for a user-defined function to return a reference. Those last two sentences impressed me. With this, you could do things like coolHostFn() = value (valid syntax, btw). So my question is: Are there any EcmaScript implementations that define host function objects which result in Reference values?

  • Why this button doesn't cause triple postback?

    - by focus
    We have developed a page with a asp.net and debugging it accidentally we have discovered on our page button with the next code on onclik attribute onclick="__doPostBack('ctl00$FormPlace$m_userTaskMarkAsUnreadButton',''); __doPostBack('ctl00$FormPlace$m_userTaskMarkAsUnreadButton','');WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$FormPlace$m_userTaskMarkAsUnreadButton", "", true, "", "", false, false))" It seems that the button do three postbacks but when we click it only cause on postback. With this code seems that de button will cause three postbacks!! We have try it with Internet Explorer and Firefox and the button only cause on postback always. Are browsers who avoid that the button do three postback ? Or Is Asp.net server who avoid the three postback? We don't understand why the button behaves correctly if onclick attribute has three call to do Postbacks. Thanks

Ex: var elem = $("body").append(""); $(elem).show(); but it seems that .append returns the whole jQuery object.. am i supposed to use an ID for the inserted element and always reference it by it?? i really hope that there is a smarter move here. I'm used to do it like that from Prototype..

  • Ajax response is taking time to populate.

    - by Rachel
    I am having an util class which is not owned by me. I am calling one of the method of that util class which inturn calls one ajax function. And gives me response back. I need to make a decision depending on the response object. The problem is that response object takes some time to populate(mili seconds). var selector = dojo.byId("SelectorId"); var theChart = new chart( selector, 135, 92, style, frequency, time); if(theChart.data ===null){ console.log("No response"); }else{ Console.log("Use response data"); } and chart( selector, 135, 92, style, frequency, time); is not owned by me. chart() is from util class. above snippet works fine with break point. But when I remove the breakpoint it starts going in "if" block always. Hows can I solve this issue.

  • run a function when a user clicks on any list element

    - by sova
    This is probably a very common question, but I was unable to find an answer myself; All my list elements call the function setQuery like this onClick="admin_stats.setQuery(this);" rather than [hardcode] add this to every list element, is there a way to simply have it run when a list element is clicked? I'm not very familiar with jQuery Live or binding/unbinding, but I think they would play a role here? Before I reinvent a rather square-looking wheel I thought I might ask =)

    - by Peter Clark
    I have a span, eg: <p>Here is a sentence <span id="rotate">this</span> is what changes</p> and I'd like the contents of that span to change every few moments between a list of terms, so the contents might change to be: <span id="rotate">then</span> <span id="rotate">thus</span> and so on. I'd like the text to fade out and then the new text fade in. Whats the best way to do this via jquery?

  • GEvent.addListener(...) return?

    - by user354436
    Hello, my Question is as follows: What does GEvent.addListener(map, "click" function(){...}) return into the callback function? I don't find any information in the GMaps reference at all, can you show me some? The only thing I found out was that there are two parameters, "overlay" and "latLng" that are passed. The name of these parameters should not be of interest right? I could also name them "foo" and "bar" as far as I know. But the parameter "overlay" seems to be empty anyway? Also I have problems passing these two parameters directly into a callback function I created myself which looks like that... GEvent.addListener(gmap, "click", generateMarker(overlay, latLng)); ... instead of writing the following, which actually works fine. GEvent.addListener(gmap, "click", function(overlay, latLng) { generateMarker(overlay, latLng); });

  • Is there a more elegant solution than an if-statement with no else clause?

    - by Jay
    In the following code, if Control (the element that trigers Toggle's first OL) is not Visible it should be set Visible and all other Controls (Controls[i]) so be Hidden. .js function Toggle(Control){ var Controls=document.getElementsByTagName("ol",document.getElementById("Quote_App")); var Control=Control.getElementsByTagName("ol")[0]; if(Control.style.visibility!="visible"){ for(var i=0;i<Controls.length;i++){ if(Controls[i]!=Control){ Reveal("hide",20,0.3,Controls[i]); }else{ Reveal("show",20,0.3,Control); }; }; }else{ Reveal("hide",20,0.3,Control); }; }; Although the function [Toggle] works fine, it is actually setting Controls[i] to Hidden even if it is already. This is easily rectified by adding an If statement as in the code below, surely there is a more elegant solution, maybe a complex If condition? .js function Toggle(Control){ var Controls=document.getElementsByTagName("ol",document.getElementById("Quote_App")); var Control=Control.getElementsByTagName("ol")[0]; if(Control.style.visibility!="visible"){ for(var i=0;i<Controls.length;i++){ if(Controls[i]!=Control){ if(Controls[i].style.visibility=="visible"){ Reveal("hide",20,0.3,Controls[i]); }; }else{ Reveal("show",20,0.3,Control); }; }; }else{ Reveal("hide",20,0.3,Control); }; }; Your help is appreciated always.
