function loadDoc() { var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { myFunction(this); } }; xhttp.open("GET", "http://10.114.56.217:8080/Online_shopping_cart/services/smartphonelist", true); xhttp.send(); } function myFunction(xml) { var i; var xmlDoc = xml.responseXML; var table="<tr><th>TYPE</th><th>MAKE</th><th>PRICE</th><th>MODEL</th><th>ID</th><th>Select</th></tr>"; var x = xmlDoc.getElementsByTagName("itemnumber"); for (i = 0; i <x.length; i++) { table += "<tr><td>" + x[i].getElementsByTagName("type")[0].childNodes[0].nodeValue + "</td><td>" + x[i].getElementsByTagName("make")[0].childNodes[0].nodeValue + "</td><td>"+ x[i].getElementsByTagName("price")[0].childNodes[0].nodeValue + "</td><td>" + x[i].getElementsByTagName("model")[0].childNodes[0].nodeValue + "</td><td>"+ x[i].getElementsByTagName("id")[0].childNodes[0].nodeValue + "</td></tr>"; } document.getElementById("dem").innerHTML = table; }

I am not much experienced with javascript, as of your question need to add button in each row with different identifier, so on brief there are various way of doing it and one of the way is below, 我对javascript没有太多经验，因为您的问题需要在每行中添加具有不同标识符的按钮，因此简要来说，有多种方法可以使用，其中一种方法如下，
When you insert contents in table u can there itself create a button for each row same like html but you can add suffix of incremental number to button name.
当您在表u中插入内容时，它本身可以为每行创建一个按钮，例如html，但您可以在按钮名称后添加增量编号的后缀。 (like : name0, name1) as directly concatenate i with button name. （例如：name0，name1）直接与按钮名称连接在一起。 on click on every function call same function with that button name, and in function extract suffix number from button name.
在每个函数上单击时，都使用该按钮名称调用相同的函数，然后在函数中从按钮名称中提取后缀号。 now with that number you can find the what need to be send in next request.
现在使用该号码，您可以找到下一个请求中需要发送的内容。
This not might be perfect solution but yes it will help you. 这可能不是完美的解决方案，但是可以，它将为您提供帮助。
Thank You 谢谢
