从对象字面量模式返回值

发布于 2024-10-03 20:09:59 字数 522 浏览 6 评论 0原文

大家好，想知道是否有人可以帮助我，我正在使用对象文字模式来组织我的代码（我是这个模式的新手）。我试图从函数返回变量的值，但它不断返回整个函数 - 有人可以告诉我我做错了什么吗这里是我的代码片段 -

    'teamStatusTableHeight': function() {
    var theHeight = $(".teamStatusTable").height() - 130;
    return theHeight;
},
'numOfTeamMembers': function() {
    var numTeams = $(".teamStatusTable tr").length;
    return numTeams
} ,
'scrollDistance': function() {
    var scroll = teamStatus.teamStatusTableHeight / teamStatus.numOfTeamMembers + 30;
    return scroll;
}

任何帮助将不胜感激。

Hi guys wondering if someone can help me, I am using the object literal pattern to organise my code (I'm new to this pattern). I am trying to return the value of a variable from a function but it keeps returning me the whole function - could someone tell me what I am doing wrong here is a snippet from my code -

    'teamStatusTableHeight': function() {
    var theHeight = $(".teamStatusTable").height() - 130;
    return theHeight;
},
'numOfTeamMembers': function() {
    var numTeams = $(".teamStatusTable tr").length;
    return numTeams
} ,
'scrollDistance': function() {
    var scroll = teamStatus.teamStatusTableHeight / teamStatus.numOfTeamMembers + 30;
    return scroll;
}

Any help would be greatly appreciated.

您需要调用这些函数，如下所示：

var scroll = teamStatus.teamStatusTableHeight() / teamStatus.numOfTeamMembers() + 30;

注意添加的()，以便您使用的是函数的结果，而不是函数本身他们自己。

You need to call those functions, like this:

var scroll = teamStatus.teamStatusTableHeight() / teamStatus.numOfTeamMembers() + 30;

Note the added () so you're using the result of the functions, not the functions themselves.

这对我来说看起来不错。也许您实际上并没有调用该函数？

// get the function
MyObj.teamStatusTableHeight

// run the function
MyObj.teamStatusTableHeight()

你把括号去掉了吗？他们需要实际执行该功能。否则它们只是提供对函数对象本身的访问。

That looks fine to me. Perhaps you are not actually calling the function?

// get the function
MyObj.teamStatusTableHeight

// run the function
MyObj.teamStatusTableHeight()

Did you leave off the parentheses? They are required to actually execute the function. Otherwise they simply provide access to the function object itself.
