ajaxform或者ajaxpost,导致echo / var_dump 打断php程序的运行?
一个很奇怪的事情,页面有个链接xxx,使用ajax, 点击之后转到在Thinkphp的controller,我在这个controller里面加了echo或者var_dump想看一些参数值,结果不执行了,页面不会跳转了。 把echo 或 var_dump去掉,就执行成功了。
不明白这个为什么,难道是执行过程不能把打断?
如果是ajax导致的,请问如何查看controller里的数据呢?

不会不会不会
不会不会不会
这个跟你在ajax对返回结果的处理有关
echo输出内容了啊
目前不知道你的页面代码,如果是ajax请求controller,那么问题应该是你echo了内容,导致返回的不是json格式的信息,页面无法处理,所以没什么反应了
会的,ajax调试推荐用firephp或者socketlog
不会 继续debug
echo输出的内容使json无法正常解析。
ajax用了json类型,所以echo会破坏json格式,造成js解析不了,其实是有数据返回了的,可以打开浏览器的“元素审查”就是开发者工具抓包看响应
不会的。应该是数据格式的问题。
估计是楼主用的ajax的原因,因为不echo数据的时候,返回的数据是正常的,跳转也是在success成功后进行跳转,而echo后,返回的数据则不正常,就没执行跳转
