在JAVASCRIPT中添加窗户
原标题:Instanciate with window object in JAVASCRIPT

i) 存在一个与窗户交织的班子的问题,即有名称空间叫UTIL,而且有:

var UTIL = { Classes : {}};

UTIL.Classes.ObservationVal = function(state, id, type, context, performer, addresee, query) {
    this.query = query;
    SPEECH.Classes.ActionVal.call(this,state, id, type, context, performer, addresee);
}

UTIL.Classes.ObservationVal.prototype = new SPEECH.Classes.ActionVal();
UTIL.Classes.ObservationVal.prototype.constructor = SPEECH.Classes.ObservationVal;

after, i have this code:

var name = "ObservationVal";
var clStr = "UTIL.Classes." + name;
var obj = new window[clStr]();

最后一行显示了错误:“窗口不是构造者”

我不理解,为什么在从名称空间界定“观察”类别时,就没有客观。

function ObservationVal(state, id, type, context, performer, addresee, query) {
//..
}

the instanciate with window works ok. Thanks.

最佳回答

这是因为foo[“bar.baz”]foo.bar.baz不相同。 或许需要<代码>window等内容。 UTIL.Classes[name] here.
