    [CLOSED][3.0 CORE] Ext core still have problems with json encode


    Ext core still have problems with json encode function. I believe that Ext.isDate is missing.

    The Ext.encode returns the following error: TypeError: Ext.isDate is not a function.

    Which version? isDate doesn't appear in the SVN version of Ext core anywhere.

    Just go to http://extjs.com/playpen/ext-core-la...amples/rating/

    And type the following into the Firebug console:

    Code:
    Ext.util.JSON.encode({d: new Date()})

    This is odd, the core code doesn't contain anything to do with isDate, perhaps something is weird with the build script.

    trunk/src/core/util/JSON.js:

    Code:
        this.encode = function(o){
            if(typeof o == "undefined" || o === null){
                return "null";
            }else if(Ext.isArray(o)){
                return encodeArray(o);
            }else if(Ext.isDate(o)){
                return Ext.util.JSON.encodeDate(o);

    Not what I'm seeing:

    Code:
    this.encode = isNative ? JSON.stringify : function(o){
            if(typeof o == "undefined" || o === null){
                return "null";
            }else if(Ext.isArray(o)){
                return encodeArray(o);
            }else if(Object.prototype.toString.apply(o) === '[object Date]'){
                return Ext.util.JSON.encodeDate(o);

    Of course the obvious answer is just include isDate() in core, since the code saving from not including it is relatively minor.

    OK, the build was wrong.

    Because on that test page, Ext.util.JSON.encode.toSource() prints

    Code:
    "(function (o) {if (typeof o == "undefined" || o === null) {return "null";} else if (Ext.isArray(o)) {return encodeArray(o);} else if (Ext.isDate(o)) {return Ext.util.JSON.encodeDate(o);} else if (typeof o == "string") {return encodeString(o);} else if (typeof o == "number") {return isFinite(o) ? String(o) : "null";} else if (typeof o == "boolean") {return String(o);} else {var a = ["{"], b, i, v;for (i in o) {if (!useHasOwn || o.hasOwnProperty(i)) {v = o[i];switch (typeof v) {case "undefined":case "function":case "unknown":break;default:if (b) {a.push(",");}a.push(this.encode(i), ":", v === null ? "null" : this.encode(v));b = true;}}}a.push("}");return a.join("");}})"

    Something's funny with SVN.

    I just explicitly did an SVN Update on trunk/core/src/util, and it updated JSON.js with the code fix that Tommy put in on the 2nd.

    That was after I did an SVN Update on the whole ext directory earlier today.

    Could be that when the build is done, the SVN checkout is not working well.

    the <ext>/core directory is marked as an external svn resource, so it won't be updated when updating <ext>. you'll need to explicitly update <ext>/core (using tortoisesvn / command line) to get the latest core.
