Eval

qmllint 将此警告类别拼写为[eval] 。

请勿使用 eval

发生了什么？

您在代码中使用了 `eval `。

为什么这样做不好？

eval 方法运行缓慢且可能存在安全隐患。eval 会将其参数作为独立的 JavaScript 脚本执行，这会给执行过程增加额外开销。传递给eval 的参数可能成为远程代码执行攻击的载体。

示例

import QtQuick

Item {
    function f() {
        let myString = "x",
        myObject = {
            x: 10
        },
        value = eval("myObject." + myString);
    }
}

要解决此警告，请重写代码，确保其中不包含任何eval 调用。

import QtQuick

Item {
    function f() {
        let myString = "x",
        myObject = {
            x: 10
        },
        value = myObject[myString];
    }
}
