Question

我有以下代码片段，当点击网格中的编辑按钮弹出一个窗口时调用该代码片段

edit: function(e) {
$('input[name="prods"]').each(function()
{
    var textarea = $(document.createElement('textarea'));
    textarea.text($(this).val());

    $(this).after(textarea).remove();
}); 
}

文本框输入类型转换为textarea，工作正常。

将它转换为textarea后，如何将textarea的值赋给$('input[name="prods"]') 当点击弹出窗口的保存按钮？

请尝试使用以下代码段。我们必须从textArea中检索值并将其值分配给model属性。

如果有任何疑虑，请告诉我。

Answer 2

这可能是val和text的混合吗？ textarea.text似乎错了，通常是textarea.val（＆＃39;无论如何＆＃39;）

这里包括：

jQuery get textarea text

Answer 3

您也可以使用此方法..

<div class="ref">
<input type="text" name="prod" value="TEST"/>
</div>


jQuery('.edit').click(function(){

var val = jQuery('input[name="prod"]').val()
jQuery('.ref').html('<textarea name="prod">'+val+'</textarea>');

});

将输入类型文本转换为textarea并将值赋回输入类型文本
