jQuery，使用.each（）以多种形式提交（）

Question

First off, I realize this is not an optimal solution, but the actual production environment is a product of a drunken orgy involving Magento and a lot of cheap plugins, so don't judge me too harshly. 首先，我意识到这不是一个最佳解决方案，但实际的生产环境是醉酒狂欢的产物，涉及Magento和许多廉价插件，因此不要对我太苛刻。 I can't be held responsible for other peoples' messes. 我对别人的混乱不负责任。

I'm trying to submit multiple forms from one page using jQuery. 我正在尝试使用jQuery从一页提交多种表单。 It works fine in IE and FF. 在IE和FF中工作正常。 Page has four forms, which I loop through them in JS to see if their checkbox is checked and then submit them one by one, using .each() and .submit() . Page有四种形式，我在JS中循环浏览它们以查看是否选中了它们的复选框，然后使用.each()和.submit() .each()提交。 In Chrome, jQuery(this).submit() does not fire until after you have completely exited the function, and then it only actually submits the last form. 在Chrome中，直到完全退出该函数后， jQuery(this).submit()才会启动，然后它仅实际提交最后一个表单。

Chrome doesn't treat target="_blank" like the other browsers. Chrome浏览器不像其他浏览器那样对待target =“ _ blank”。 Try _tab, or dynamically changing them $(this).attr('target', '_'+$(this).attr('id')); 尝试_tab，或动态更改它们$(this).attr('target', '_'+$(this).attr('id'));
