[Vue warn]: Error in render: "syntaxerror:unexpected tokens ' in JSON at position 1"

One, the scene:

String to object;

var str = "{' BankRate ': 5, ' Yinguo ': 0}"

Two, Operation:

Json.parse (str), error

[Vue warn]: Error in render: "syntaxerror:unexpected tokens ' in JSON at position 1"

Three, Reason:

Using the parse method, the requirement is strict, and the JSON must be both K and value wrapped in double quotation marks;

Ex: "{" BankRate ": 5," Yinguo ": 0}"

Four, Solution: No parse, choose eval ()

Eval (' (' + str + ') ') note the need to wrap a pair of parentheses outside the JSON character note: IE8 (compatibility mode), IE7 and IE6 can also use eval () to convert a string to a JSON object, but this is not recommended. This way unsafe eval executes an expression in a JSON string.
