运行上面的html文件 可以显示 1 2 3 4 5
可一单击超链接时，firefox的debug显示 check is not defined
不是已经innerHTML进来了么，而且奇怪的是那个$page如果不加零的话显示的object element，望朋友解答！！！
——解决方案——————–
这样呢
function check(node) {
var parameter = “page=” + node;
var nokia = ajax();
//alert(nokia);return;
nokia.open(‘POST’,”process.php”,true);
nokia.setRequestHeader(‘Content-Type’,’application/x-www-form-urlencoded’);
nokia.send(parameter);
nokia.onreadystatechange = function () {
if(nokia.readyState==4 && nokia.status==200) {
document.getElementById(‘span1’).innerHTML = this.responseText;
}
}
}
window.onload = check(node);
——解决方案——————–
- JScript code
window.onload = function (){ check(1);}function check(node) { var parameter = "page=" + node; var nokia = ajax(); //alert(nokia);return; nokia.open('POST',"process.php",true); nokia.setRequestHeader('Content-Type','application/x-www-form-urlencoded'); nokia.send(parameter); nokia.onreadystatechange = function () { if(nokia.readyState==4 && nokia.status==200) { document.getElementById('span1').innerHTML = this.responseText; } }}
