no-alert

禁止使用 alert、confirm 和 prompt

JavaScript 的 alert、confirm 和 prompt 函数被广泛认为是作为 UI 元素的突兀，应该被更合适的自定义 UI 实现所取代。此外，alert 经常在调试代码时使用，应在部署到生产之前将其删除。

¥JavaScript’s alert, confirm, and prompt functions are widely considered to be obtrusive as UI elements and should be replaced by a more appropriate custom UI implementation. Furthermore, alert is often used while debugging code, which should be removed before deployment to production.

alert("here!");

规则详情

¥Rule Details

此规则旨在捕获应删除的调试代码和应替换为不那么突兀的自定义 UI 的弹出 UI 元素。因此，它会在遇到未隐藏的 alert、prompt 和 confirm 函数调用时触发警告。

¥This rule is aimed at catching debugging code that should be removed and popup UI elements that should be replaced with less obtrusive, custom UIs. As such, it will warn when it encounters alert, prompt, and confirm function calls which are not shadowed.

此规则的错误代码示例：

¥Examples of incorrect code for this rule:
