HomeBackend DevelopmentPHP Tutorial分享一个js文件中嵌套php会出错的问题

前提:

使用ThinkPHP。后台传一个变量到html页面:$this->assign("variable", $variable);

问题:

在html页面中嵌套js代码,在js的代码中输出这个变量:

<script language="JavaScript">    var variable =<?php echo $variable;?>;    alert(variable);    //这样是可以正常输出的</script>


将上面的代码迁移到js文件variable.js中,再在该html页面引入这个js文件,这时候就会出错,不但是输出不来,还是造成js错误,js代码都运行不了。

我的解决方法是:

  1. 写隐藏标签

    再在js中获取该元素的值

  2. 如果你有使用jq的话,你可以在标签中添加属性:

    我是div

        js: var variable =$("div").attr("data-value");

上面两种方法都有个缺陷,就是variabe都是可见的,只要别人“审查元素”就能看见你的variable是什么,是保密的数据就不建议这样做了。
