项目中多次使用了iframe,但是操作起来是比较麻烦,项目中的现实情况是最外面是一个form,里面嵌套一个iframe,下面是一个其他的数据,在form提交的时候将iframe的数据和其他的数据一块提交。
现在采用的是最原始的办法就是在form提交之前,将iframe里面的input,select,textarea都clone到外面的form里面,然后进行表单提交。
另外,测试发现,textarea和select的jquery的clone方法有问题,textarea和select的值clone的时候会丢掉,发现这个是jquery的一个bug,在网上发现一个插件,下载地址如下:https://github.com/spencertipping/jquery.fix.clone/blob/master/jquery.fix.clone.js,上不了的可以看下代码,比较简单。就是在clone的时候将val再重新赋值一下,如果知道这个了,也可以不用这个插件,自己写。
// Textarea and select clone() bug workaround | Spencer Tipping
// Licensed under the terms of the MIT source code license // Motivation.
// jQuery's clone() method works in most cases, but it fails to copy the value of textareas and select elements. This patch replaces jQuery's clone() method with a wrapper that fills in the
// values after the fact. // An interesting error case submitted by Piotr Przybył: If two <select> options had the same value, the clone() method would select the wrong one in the cloned box. The fix, suggested by Piotr
// and implemented here, is to use the selectedIndex property on the <select> box itself rather than relying on jQuery's value-based val(). (function (original) {
jQuery.fn.clone = function () {
var result = original.apply(this, arguments),
my_textareas = this.find('textarea').add(this.filter('textarea')),
result_textareas = result.find('textarea').add(result.filter('textarea')),
my_selects = this.find('select').add(this.filter('select')),
result_selects = result.find('select').add(result.filter('select')); for (var i = 0, l = my_textareas.length; i < l; ++i) $(result_textareas[i]).val($(my_textareas[i]).val());
for (var i = 0, l = my_selects.length; i < l; ++i) result_selects[i].selectedIndex = my_selects[i].selectedIndex; return result;
};
}) (jQuery.fn.clone);
