Question

我在从xml请求中选择表中的行时遇到问题。请看下面的例子：

我的网络很相似。是否可以使用JS功能让我在点击具有已定义类的行后更改背景？我想responseText不会返回类名。目前我的JS函数可以在任何地方使用，但在DIV中不显示xml请求。

order.php：

// -that is a part from page that connect with sql base. it is what is return to main page and it works.[for example 3 squares with orderd detail]
while($num!=0) {
    $row = $result->fetch_assoc();
    echo '<div class="order"><p id="data">Date:'.$row['Whens'].'</p><p id="types">'.$row['Types'].' '.$row['Brand'].'</p><br><p id="whats">'.$row['Whats'].' </p><br> <p id="detai"> '.$row['Detai'] .'</p></div>';
    $num--;
}

的index.php：

// -this is a part from main page where I get data from order.php - it works.
function showUser(id){
    if (window.XMLHttpRequest) {
        var xmlhttp=new XMLHttpRequest();
    }
    xmlhttp.onreadystatechange=function() {
       document.getElementById("order_t").innerHTML=this.responseText;
    }
    xmlhttp.open("GET","order.php?q="+id,true);
    xmlhttp.send();
}

JS功能

// - I try use below to change background in div's with class="order" which I get from order.php. It does't work
$(".order").click(function(){
    $(this).addClass("selected2").siblings().removeClass("selected2");
})

如何在XML AJAX上执行JS请求responseText
