Question

我有一个包含以下PDF文件的文件夹：

0001 - 101 - Almonds 1kg.pdf
0001 - 396 - Almonds 6 x 1kg.pdf
0001 - 400 - Almonds 10 x 1kg.pdf

我试图创建一个window.open函数来跟踪目录并打开从下拉菜单中选择的特定PDF。

作为示例，这是文件的存储位置： C：\ Users \ test \ Desktop \ work

这是我的代码：

document.addEventListener("DOMContentLoaded", function(){
  

document.querySelector('.btn-1').addEventListener('click', function(){
	var formOne = document.querySelector('#Pcode');
  	var formTwo = document.querySelector('#Wcode');  
  	var pcode = document.querySelector('.Pcode-val');
  	var wcode = document.querySelector('.Wcode-val');
  	var opt = getSelectedOption(pcode);
  	var wpt = getSelectedOption(wcode);
          
 function getSelectedOption(pcode) {
    var opt;
    for ( var i = 0, len = pcode.options.length; i < len; i++ ) {
        opt = pcode.options[i];
        if ( opt.selected === true ) {
            break;
        }
    }
    return opt;
};


 function getSelectedOption2(wcode) {
    var wpt;
    for ( var i = 0, len = wcode.options.length; i < len; i++ ) {
        opt = wcode.options[i];
        if ( opt.selected === true ) {
            break;
        }
    }
    return wpt;
};

       window.open(
  'C:\Users\test\Desktop\work' + opt.value + ' - ' + wpt.value,
  '_blank' // <- This is what makes it open in a new window.
);

        

});




  
});

	<script type="text/javascript" src="app.js"></script>

<body>


	<form id="Pcode">
		<select class="Pcode-val">
			<option value="0001">Almonds</option>
			<option value="0002">Ground Almonds</option>
		</select>
		<button type="button" class="btn-1">Submit</button>
	</form>

		<form id="Wcode">
		<select class="Wcode-val">
			<option value="101">1kg</option>
		</select>
	</form>



</body>
</html>

       window.open(
  'C:\Users\test\Desktop\work' + opt.value + ' - ' + wpt.value,
  '_blank' // <- This is what makes it open in a new window.
);

我尝试过的是，放入目录并添加opt和wpt值（这些是HTML文件中的options的值）。这是我所知道的。如何在不完全输入字符串但部分字符串且仍以0001-101.pdf的形式打开0001-101 Almonds.pdf文件的情况下打开文件？
