<form action="test3.php" method="POST">
<input value='' type="hidden" id='getpath' name='x1' />
<input value='sdf' name='x2' />
<div class="parent">
<input type="file" class="file">
</div>
<input type="submit" value="Submit" />
</form>
</body>
</html>
<script>
$(".parent").on("change",".file",function(){
var getpath=$(this).val();
alert(getpath);
$('#filepath').val(getpath);
});
</script>
用parent把file input包起来是为了防止onchange事件一次调用之后失效．
二 test3.php
<?php
error_log('WBW'.'|'.date('Y-m-d H:i:s', time()).'|'.print_r($_REQUEST,1)."\r\n",3,'/tmp/debug.log');
本人用的ubuntu系统，以上为将表单各个参数打印到临时日志文件中．
三 结果展示
①点击浏览按钮，并选择文件
②点击submit按钮，并选择文件确定
wbw@wbw-All-Series:/tmp$ tail -f debug.log
[x1] => C:\fakepath\140C.xlsx
[x2] => sdf
)
WBW|2019-12-24 18:36:45|Array
(
[x1] => C:\fakepath\ll.txt
[x2] => sdf
)
获取文件绝对路径成功!
