Question

我已经看到了上述问题的许多解决方案，但没有一个属于我的类别。我的服务器正在响应正确的json。无法确定导致问题的原因。我将状态显示为0，状态文本显示为错误。那真令人恶心。问题在于deleteimage（）函数。 mi8在处理事件的方式上有问题。如果有人能弄清楚它会很好。在此之后差不多有一天。感谢帮助。

Answer 1

我尝试向服务器发送请求时需要使用相对路径，其中i使用绝对路径，这是我获得状态为0的原因。

url: "deleteOthersDesignImgPath"

而不是

url: "http://192.168.0.2:8080/JaydeepSarees/deleteOthersDesignImgPath",

ajax中的服务器响应是错误功能而不是成功
