前端之家收集整理的这篇文章主要介绍了
ajax php 实现写入数据库，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
首先需要一个带输入表格.
<div class="codetitle"><a style="CURSOR: pointer" data="75935" class="copybut" id="copybut75935" onclick="doCopy('code75935')"> 代码如下:
<div class="codebody" id="code75935">
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<
Meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script src="submit.js" language="javascript">
Insert 知识点
<form name="insertForm">
<label for="question">知识点
<input name="question" type="text"/>
<label for="answer"> 答案
<input name="answer" type="text"/>
<input name="confirm" value="
添加" type="button" onclick="getValue();">

需要js来处理提交数据到服务器上以及从服务器
获取提交后的返回数据. submit.js
代码如:
<div class="codetitle">
<a style="CURSOR: pointer" data="67649" class="copybut" id="copybut67649" onclick="doCopy('code67649')"> 代码如下: <div class="codebody" id="code67649">

var xmlHttp;
function getValue(){
alert("getvaluel");
var question =document.insertForm.question.value;
// alert(question);
var answer = document.insertForm.answer.value;
// alert(answer);
submit(question,answer);
};
function submit(question,answer){
xmlHttp=GetXmlHttpObject();
if (xmlHttp==null)
{
alert ("Your browser does not support AJAX!");
return;
}
xmlHttp.onreadystatechange =function(){
if(xmlHttp.readyState ==4){
alert(xmlHttp.responseText);
}
};
var url = "insert1.
PHP";
xmlHttp.open("post",url,true);
xmlHttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded; charset=utf-8");
xmlHttp.send("question="+question+"&answer="+answer); }
function GetXmlHttpObject()
{
var xmlHttp=null;
try
{
// Firefox,Opera 8.0+,Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
// Internet Explorer
try
{
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
}
return xmlHttp;
}
