本文解析了一种常见的JavaScript动态执行异常问题，即当尝试通过innerHTML属性插入JavaScript代码时，未正确引用参数导致的问题。详细说明了如何通过为参数添加引号来避免浏览器将参数误认为变量名而非其值。

摘要生成于 C知道 ，由 DeepSeek-R1 满血版支持， 前往体验 >

动态js执行异常：obj.innerHTML="javascript:delete(param)"，

原因：参数 没有加引号，浏览器会把参数：param当做变量名，而不是它们的值，

这时需要加引号：obj.innerHTML="javascript:delete(' "+param+" ')"，

这样浏览器会参数当成字符串处理了。

例如：

obj.innerHTML="javascript:delete(param)"，如果参数param="fileName"，

那么浏览器会把obj.innerHTML="javascript:delete(fileName) 中fileName当成变量名，

而不是字符串“fileName” （不过，如果参数param取数字的话，js能顺利执行）。

关于object.innerHTML的一点发现

有时候我们想要用object.innerHTML来作为条件，通过条件判断来实现我们想要达到的效果，但是往往会出错，或者没有效果显示，今天我就我遇到的问题以及解决方法，做个总结： 我想实现这么一个效果，在一个区域点击以后实现如下效果： 开始区域的内容是1，点击以后在下一行显示2，再次点击下一行显示3，再次点击整个区域只显示4，再次点击整个区域只显示5，再次点击整个区域消失 条件判断是这么写的

innerHTML 属性用于获取或替换 HTML 元素的内容。 语法: Object.innerHTML 注意: 1.Object是获取的元素对象，如通过document.getElementById("ID")获取的元素。 2.注意书写，innerHTML区分大小写。 innerHTML javascript JavaScript是一种基于对象、事件驱动
