这是我从 w3schools 学到的用于加载 AJAX 的脚本。
document.getElementById("sendInvoiceButton").innerHTML = '';
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("invoiceIDStatus").innerHTML = '';
document.getElementById("invoiceIDStatus").innerHTML=xmlhttp.responseText;
}
}
var invoiceID = document.getElementById("cred_form_4684_1_wpcf-ticket-invoice-id").value;
var text = "invoiceID=" + encodeURIComponent(invoiceID);
document.getElementById("invoiceIDStatus").innerHTML = '<img src="http://www.lessons.com.sg/freshbooks/demo_wait.gif" />';
xmlhttp.open("POST","/freshbooks/getInvoice.php",true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send(text);
}
我只能输出 1 xmlhttp.responseText;
我也想将发票号码发送到文本框。我怎样才能做到这一点?
