Question

var temp = { "100" = ["submenu 4", "submenu 5", "submenu 6"],
        "136" = ["submenu 10", "submenu 11", "submenu 12"],
        "125" = ["submenu 19", "submenu 20", "submenu 21"],
        "99"  = ["submenu 16", "submenu 17", "submenu 18"], 
        "77"  = ["submenu 13", "submenu 14", "submenu 15"],
        "70"  = ["submenu 1", "submenu 2", "submenu 3"],
        "4"  = ["submenu 7", "submenu 8", "submenu 9"] };

如何用：符号替换 = ？或者如何在jquery函数中迭代上面的temp？

请提供解决方案。

Answer 1

此JSON无效，您无法在temp中替换'='，因为temp会在尝试将此值赋给它时引发错误。在代码中替换它以使其工作，否则您无法对此进行迭代。

Answer 2

var temp = '{ "100" = ["submenu 4", "submenu 5", "submenu 6"],
        "136" = ["submenu 10", "submenu 11", "submenu 12"],
        "125" = ["submenu 19", "submenu 20", "submenu 21"],
        "99"  = ["submenu 16", "submenu 17", "submenu 18"], 
        "77"  = ["submenu 13", "submenu 14", "submenu 15"],
        "70"  = ["submenu 1", "submenu 2", "submenu 3"],
        "4"  = ["submenu 7", "submenu 8", "submenu 9"] }';
temp = temp.replace(/=/g,":");
temp = JSON.parse(temp);

这样的东西？

Answer 3

除了将=标志更改为:之外，没有其他有效的解决方案。在这一点上完全停止。这实际上是解决这个问题的唯一方法，并使其成为有效的JavaScript对象。

如果从外部源获取此信息，可以对其进行一些正则表达式更改。如果是您的代码，则只需更改符号即可。
