Meteor 模板助手的全局函数 [英] Global function for Meteor template helper

问题描述

我已经注册了一个这样的全局函数:

I have registered a global function like this:

Handlebars.registerHelper('dialogBoxOptions', function (callbackFunctionName){
    return {
        callBack: callbackFunctionName
    };
});

但是当我尝试如下访问它时，我得到 dialogBoxOptions 未定义

but when I try to access it as below I get dialogBoxOptions is not defined

Template.myLlist.helpers({
    dOpt: dialogBoxOptions('dlgCB')
});

我已将其作为全局把手助手和常规 javascript 函数进行了尝试，但得到了相同的结果.

I have tried this as a global handlebars helper and a regular javascript function but get the same result.

推荐答案

您无法通过这种方式访问​​车把助手，您可以在模板中访问它们:

You can't access handlebars helpers this way you can access them in the template:

<template name="myList">
     {{dialogBoxOptions.callback 'something'}}
</template>

如果你想像现在一样在你的助手中访问它，你应该注册一个全局方法.你可以把它放在像 /lib/helpers.js

If you want to access it in your helper like you are doing now you should register a global method instead. You could put this in a file like /lib/helpers.js

dialogBoxOptions = function (callbackFunctionName){
    return {
        callBack: callbackFunctionName
    };
}

另外，如果你想制作一个全局模板助手，现在的语法是:

Also if you want to make a global template helper, the syntax is now:

Template.registerHelper("dialogBoxOptions", function (param2) {
    return true;
});
