Question

e.target指向表单元素。我正在尝试遍历每个输入元素并收集名称和值，以便我可以将它们作为参数传递给a .load()。 .each()迭代器永远不会找到<input>元素，因此在不处理任何内容的情况下退出。表单包含一个包含输入的div元素。

var formData = {};
$(e.target).has(":input").each(function(){
    formData[$(this).name] = $(this).value;
});

表单html：

<div id="partner-settings-form" class="ui-dialog-content ui-widget-content" scrolltop="0" scrollleft="0" style="display: block; width: auto; min-height: 67.6875px; height: auto;">         
<article class="sign_in form-dialog clearfix">
      <div class="bg-form-dlg">
        <div class="col_100 clearfix">

Answer 1

使用.serialize()，不需要重新发明轮子，交配。

$(e.target).serialize();

修改

由于.load（）使用查询字符串请求GET，而使用对象请求POST，因此.serialize（）不会删除它。解决方法是使用.ajax（）或调整代码，因为你有错误：

var formData = {}; $(e.target).find('input').each(function() { formData[$(this).attr('name')] = $(this).val(); // .attr('name') and .val() instead. });

Answer 2

尝试不同的

$(e.target).find('input').each();

为什么.each（）找不到子元素？
