[英]HTML Form Input Fields to read and write XML file
我目前正在尝试使用输入字段构建HTML表单，以读取XML文件并写回更改。 第一步是将页面加载时的值检索到输入字段中，但它不起作用
<body>
<h1>Config Page</h1>
<div>
<b>Site URL:</b> <input type="text" id="siteURL" value="site..."/></span><br>
<b>Site Collection:</b> <span id="siteCollection"></span><br>
</div>
<script>
var xmlhttp, xmlDoc;
xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET", "/Configuration/config.xml", false);
xmlhttp.send();
xmlDoc = xmlhttp.responseXML;
document.getElement
document.getElementById("siteURL").value.innerHTML =
xmlDoc.getElementsByTagName("siteURL")[0].childNodes[0].nodeValue;
document.getElementById("siteCollection").innerHTML =
xmlDoc.getElementsByTagName("siteCollection")[0].childNodes[0].nodeValue;
function myFunction() {
alert(siteURL + "is the site Url")
}
</script>
<button onclick="myFunction()">Get message value</button>
我知道XML可以顺利通过，因为siteCollection范围项目有效，但输入字段无效。
任何帮助将非常感激。
谢谢。
也许如果您使用jQuery，可以按照以下步骤进行操作

<div>
<b>Site URL:</b> <input type="text" id="siteURL" value="site..."/></span><br>
</div>
<button onclick="myFunction()">Get message value</button>
<script>
function myFunction() {
var xmlHttp = jQuery.parseXML('<?xml version="1.0" encoding="utf-8"?><config><siteURL>http://localhost/</siteURL></config>');
var xmlDoc;
xmlDoc = xmlHttp.documentElement;
$("#siteURL").val(xmlDoc.getElementsByTagName("siteURL")[0].childNodes[0].nodeValue);
}
</script>
感谢大德使我走上正确的道路。 我找到了将XML文件读入HTML输入字段形式的解决方案
对于javascript ...
var xmlpath = "../configuration/test.xml"
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET", xmlpath, false);
xmlhttp.setRequestHeader('Content-Type', 'text/xml');
xmlhttp.send("");
xmlDoc = xmlhttp.responseXML;
function loadFunction() {
$("#siteURL").val(xmlDoc.getElementsByTagName("siteURL")[0].childNodes[0].nodeValue);
}
对于页面...
<script src="/Script/form.js"></script>
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<html>
<br>Site URL (EG: http://intranet)</br>
<input type="text" id="siteURL" name="siteURL" value="blank..." />
<button onclick="loadFunction()">Load Configuration</button>
</html>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">

<script type="text/javascript">
function readXMLFile() {
var i;
var xml = new XMLHttpRequest();
xml.open('GET', 'projectRelatedData.xml', false);
xml.send();
var xmlData = xml.responseXML;
xmlData=(new DOMParser()).parseFromString(xml.responseText,'text/xml');
var projectData=xmlData.getElementsByTagName("project");
//alert(projectData.length);
for(i=0;i<projectData.length;i++)
{
var name=projectData[i].getElementsByTagName("name")[0].firstChild.data;
var imageName=projectData[i].getElementsByTagName("imagePath")[0].firstChild.data;
var pdfName=projectData[i].getElementsByTagName("pdfPath")[0].firstChild.data;
var description=projectData[i].getElementsByTagName("description")[0].firstChild.data;
var amount=projectData[i].getElementsByTagName("amount")[0].firstChild.data;
//alert("number of Project : "+projectData.length);
document.write(name+'<br>');
document.write(imageName+'<br>');
document.write(pdfName+'<br>');
document.write(description+'<br>');
document.write(amount+'<br>');
}
}
