使用jQuery从输入[type ='file']中获取文件名 [英] Get filename from input [type='file'] using jQuery

问题描述

这是上载的表单.

<form class="alert alert-info">
    <div>
        <b id = "select_file" class="span3" style="font-weight: bold; cursor: pointer; ">Please select image</b>
        <input class="span3" type="file" name="image_file" id="image_file" style="display:none " />
        <input disabled="true" type="button" value="Upload image" class="btn" />
    </div>
</form>

我使用以下脚本打开一个包含文件的窗口.我想在<b id = 'select_file'>中显示文件名.

I use the following script to open a window with files. I want to show a file name in <b id = 'select_file'>.

我该怎么做?

$('#select_file').click(function(){
    var _this = $(this);
    $('#image_file').show().focus().click().hide();

    var filename = $('#image_file').val();
    _this.html(filename);

    $('.btn').attr('disabled', false);
});

推荐答案

您必须这样对input type file的change事件执行此操作:

You have to do this on the change event of the input type file this way:

$('#select_file').click(function() {
    $('#image_file').show();
    $('.btn').prop('disabled', false);
    $('#image_file').change(function() {
        var filename = $('#image_file').val();
        $('#select_file').html(filename);
    });
});​
