Php Jquery不发送Post变量？
首先我道歉，我对jquery的了解很糟糕，但我正在学习。我写一个供个人使用的脚本时遇到了一个很大的问题，整个周末都让我很恼火。PHP可以100%工作（经过测试），只是jquery不会发送post变量 脚本允许您添加步骤以及图片和标题，底部有一个按钮，允许您“删除最后一步”或“添加另一步”，最多10步。当在浏览器上使用它并查看html时，它可以无缝地工作，名称和id会根据需要进行更改，它的工作效果非常好，而在步骤1之后，其他步骤（即步骤2步骤3步骤4）都不会在提交表单时发送变量。我在表单中使用方法post，下面是步骤加法器的javascript和html：Php Jquery不发送Post变量？,php,jquery,forms,variables,post,Php,Jquery,Forms,Variables,Post,首先我道歉，我对jquery的了解很糟糕，但我正在学习。我写一个供个人使用的脚本时遇到了一个很大的问题，整个周末都让我很恼火。PHP可以100%工作（经过测试），只是jquery不会发送post变量 脚本允许您添加步骤以及图片和标题，底部有一个按钮，允许您“删除最后一步”或“添加另一步”，最多10步。当在浏览器上使用它并查看html时，它可以无缝地工作，名称和id会根据需要进行更改，它的工作效果非常好，而在步骤1之后，其他步骤（即步骤2步骤3步骤4）都不会在提交表单时发送变量。我在表单中使用方法
