如何在angular js指令中执行字符串

Question

I am dynamically building a string which is given below

scope.gridOptions = {columnDefs : [ {
    field : username,
    displayName :USERNAME
} ]};

and storing in a string myvalue.

My requirement is that compiler has to execute this but it is treating as a string. So please suggest me how to execute a string in angular js

Answer 1

You can use JSON.parse

scope.gridOptions = JSON.parse(yourString);

Answer 2

it's unclear what you meant by saying "executing string".

First, when i saw the title i thought of JavaScript eval function ( link )

Afterwards, when i read the question, it seems you are looking to convert from/to a JSON ( what is JSON )

some suggested to use JSON.parse . i recommend you not to use it in your angular code

alternative to JSON.parse :

• angular.fromJson docs
• angular.toJson docs
