上面的代码只对foreach循环中的第一个元素进行迭代。对于其他元素,它有时只取第一个元素的值,但有时会被挤压。每个循环只能在windows load事件中执行,如何让这个脚本执行另一个事件。ajax只执行第一次迭代
这是很多需要阅读的代码,其中很多只是html。如果你删除了所有与逻辑无关的东西(注释,大部分与你的问题无关的html,php),并且只包含最低限度的问题,那么你将更有可能获得响应。 – Hecksa
我已编辑此代码..请检查此。 –
如果不仔细看,我很确定问题出在'''''''''''''''''''''''window.onload = function(){'这一行。生成的html代码有多个脚本块全部覆盖'window.onload',所以只有最后一个块会_win_。 –
