显示文件名和表格数 [英] display file name with number of forms

问题描述

我在一页上有许多表格，每个表格都有一个文件输入.当用户选择文件时，我想在相关表格内的<span class="fileNameBox"></span>中打印所选文件的名称.

I have number of forms on a page and each one has a file input. When the user chooses a file, I would like to print the name of the selected file in the <span class="fileNameBox"></span> that is inside the relevant form.

我使用的是"photoIconOn.png"图像，而不是文件上传器的输入字段.

为什么总是以第一种形式/class ="fileNameBox"打印文件名?

Why does it always print the file's name in the first form / class="fileNameBox" ?

JS:

<script>
    $(function() {
      $('input.file-field').on('change', function(e) {
        var files = this.files,
            filename = files[0].name;
        $(this).closest('form').find('.fileNameBox').html(filename);
      });
    });
</script>

推荐答案

好吧，我将回答这个问题，尽管您的工作应该可以进行. 我将您的代码复制并粘贴到小提琴中，一切正常.我唯一更改的是如何获取文件名，因为隐藏文件输入时您不是这样做的.

Well, I am going to answer this, though what you have should be working. I copy and pasted your code into a fiddle and everything works. The only thing I changed was how I got the filename since I don't how you are doing it while hiding the file input.
