我收到以下错误:

Error: Non-assignable model expression: undefined (directive: leaflet)
    at Error (<anonymous>)

除了我正在尝试调试上述错误之外,我想问一下调试代码的最佳方法是什么,因为上面的错误没有显示原始代码上的错误行但是在angular.min.js文件?

答案 0 :(得分:1)

好吧,如果我看到这个错误,我要做的第一件事就是检查具有leaflet指令的元素,然后检查其中的表达式。像这样

<div leaflet="whatever you have here is undefined"></div>

嗯,无论如何,这正是棱角分明的告诉我。

您还可以使用angular.js的Batarang调试扩展
