下拉列表项目以标记

[英]Drop Down List Item to label

I have code below for a contact form I have created. 我在下面的代码中找到了我创建的联系表单。 Is it possible to get the selected value from both drop down lists to the labels on the preview page beside both the "Location" and "Category" fields? 是否可以从两个下拉列表中将选定值从“位置”和“类别”字段旁边的预览页面上的标签中获取? Anything helps, thanks. 什么都有帮助,谢谢。

As you have it configured you could add an ID to your dropdowns and pass the data using innerHTML. 在配置完成后,您可以在下拉列表中添加ID并使用innerHTML传递数据。 Check it, I think It was what you requested. 检查一下,我想这就是你要求的。 I have just add the ID I said and what follows to your openNav() function: 我刚刚添加了我说的ID和你的openNav()函数:

document.getElementById("labelLocation").innerHTML = 
      document.getElementById("my-category").innerHTML;

document.getElementById("labelCategory").innerHTML = 
      document.getElementById("my-location").innerHTML;

 function openNav() { document.getElementById("labelLocation").innerHTML = document.getElementById("my-category").innerHTML; document.getElementById("labelCategory").innerHTML = document.getElementById("my-location").innerHTML; document.getElementById("myNav").classList.remove("collapsed"); var input = document.getElementById("txtDetail"); var value = input.value; var label = document.getElementById("labelDetail"); label.innerHTML = value; var input = document.getElementById("txtName"); var value = input.value; var label = document.getElementById("labelName"); label.innerHTML = value; var input = document.getElementById("txtNumber"); var value = input.value; var label = document.getElementById("labelNumber"); label.innerHTML = value; var input = document.getElementById("txtEmail"); var value = input.value; var label = document.getElementById("labelEmail"); label.innerHTML = value; document.getElementById("myNav").style.width = "100%"; } function closeNav() { document.getElementById("myNav").style.width = "0%"; document.getElementById("myNav").classList.add("collapsed"); } document.getElementById('file-upload').onchange = uploadOnChange; function uploadOnChange() { var filename = this.value; var lastIndex = filename.lastIndexOf("\\\\"); if (lastIndex >= 0) { filename = filename.substring(lastIndex + 1); } document.getElementById('filename').innerText = filename; var labelFile = this.value; var lastIndex = labelFile.lastIndexOf("\\\\"); if (lastIndex >= 0) { labelFile = labelFile.substring(lastIndex + 1); } document.getElementById('labelFile').innerText = labelFile; } var div = document.getElementsByClassName('dropdown-content'); for(var i =0;i<div.length;i++){ for(var j =0;j<div[i].children.length;j++){ div[i].children[j].addEventListener('click',function(){ this.parentNode.previousElementSibling.innerHTML = this.innerHTML; }) } }
