我有一个简单表单，有四个输入字段（联系人id，电话号码，姓名，称呼）。如果我输入'contact id'&按Enter按钮，字段的其余部分将自动填充，从DB检索。现在我想在表单中添加一个“Submit”按钮，这样就可以通过单击该按钮将这些信息保存到另一个DB表中。我已经尝试添加按钮，但自动填充功能不再起作用了。有人能帮忙吗？提前致谢：）下面是我的index.html文件：
<html>
<body>
<script language="javascript" type="text/javascript">
function ajaxFunction(e){
var e=e || window.event;
var keycode=e.which || e.keyCode;
if(keycode==13 || (e.target||e.srcElement).value==''){
var http; // The variable that makes Ajax possible!
try{
// Opera 8.0+, Firefox, Safari
http = new XMLHttpRequest();
} catch (e){
// Internet Explorer Browsers
try{
http = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try{
http = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e){
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
var url = "getagentids.php?param=";
var idValue = document.getElementById("agid").value;
var myRandom = parseInt(Math.random()*99999999); // cache buster
http.open("GET", "getagentids.php?param=" + escape(idValue) + "&rand=" + myRandom, true);
http.onreadystatechange = handleHttpResponse;
http.send(null);
function handleHttpResponse() {
if (http.readyState == 4) {
results = http.responseText.split(",");
document.getElementById('agfn').value = results[0];
document.getElementById('agsal').value = results[1];
document.getElementById('agtel').value = results[2];
document.getElementById('agid').value = results[3];
}
}
}
}
</script>
<form>
<table>
<tr>
<td>Contact ID:</td>
<td><input id="agid" type="text"
name="contactid" onkeyup="ajaxFunction(event)"></td>
</tr>
<tr>
<td>Tel Number:</td>
<td><input id="agtel" type="text"
name="contacttel"></td>
</tr>
<tr>
<td>Name:</td>
<td><input id="agfn" type="text"

<tr>

如果要在填充表单后添加提交按钮，可以使用innerHTML
...
if (http.readyState == 4) {
results = http.responseText.split(",");
document.getElementById('agfn').value = results[0];
document.getElementById('agsal').value = results[1];
document.getElementById('agtel').value = results[2];
document.getElementById('agid').value = results[3];
document.getElementById('buttons').innerHTML = "<input type=\"submit\" name=\"submit\" value=\"Submit\"/>"; // add Submit button by innerHTML
}
...
并在表中，将
