设置 cookie 时总是中断 JavaScript 执行 [英] Breaking JavaScript execution always when cookie is set

问题描述

是否可以在设置 cookie 时始终在 FireBug 或其他 Web 开发人员工具中中断 javascript 执行(无需明确设置 JS 断点)?

Is it possible to break javascript execution in FireBug or in some other web developer tool always when cookie is set (without setting JS breakpoints explicitly)?

document.cookie = '...';

推荐答案

下面的答案似乎不起作用铬合金.将此代码段添加到 html → head 块的开头可以正常工作:

The answer below does not seem to work in Chrome. Adding this snippet in the beginning of an html → head block works fine:

<script type="text/javascript">
    function debugAccess(obj, prop, debugGet){
        var origValue = obj[prop];
        Object.defineProperty(obj, prop, {
            get: function () {
                if ( debugGet )
                    debugger;
                return origValue;
            },
            set: function(val) {
                debugger;
                return origValue = val;
            }
        });
    };
    debugAccess(document, 'cookie');
</script>
