Question

I need to feed a javascript element with values from a Map as shown below.

My render feeds the HTML document with:

${GetFileVersion} "$UserDir\thirdParty.exe" $CurrentVersionString
StrCpy $CurrentVersion $CurrentVersionString
DetailPrint "The Current version is: $CurrentVersion"

The JS looks like this:

@(morrisDonut: Map[String, Integer])

The script stops because it dont can't find/can't use activity and steps even though its the correct types.

SOLUTION:

$.getScript('https://cdnjs.cloudflare.com/ajax/libs/raphael/2.1.2/raphael-min.js',function(){
$.getScript('https://cdnjs.cloudflare.com/ajax/libs/morris.js/0.5.1/morris.min.js',function(){

var donutData = [];
@for((activity, steps) <- morrisDonut) {
    donutData.push({label: activity, value: steps});
}

Morris.Donut({
    element: 'user_activity-donut',
    data: donutData
});
});
});

Adding " ' " and " @ " symbols seemed to work just fine

根据您的语法，我认为（我在这里推断很多）您正在使用Play框架 - 即Twirl templates。如果是这种情况，那么您只是在加载@数组的关键点缺少一些参数运算符（donutData）：

@for((activity, steps) <- morrisDonut) {
  donutData.push({label: @activity, value: @steps});
}

将Twirl指令与另一种语言混杂起来可能很棘手，因为在设计上，没有明确的＆＃34;这是我的Twirl代码的结束＆＃34;标记 - 它都是推断的。所以在你的情况下，第一行和第三行被Twirl正确解释，但第二行看起来只是一些静态内容 - 它将按原样插入。

通过添加魔术@符号，可以检测到必要的替换。
