Ajax - 如何填充隱藏字段？

Question

我是新來的阿賈克斯。我想在服務器上使用responseText填充窗體上的隱藏字段。我能夠將HTML中的responseText顯示爲innerHTML。我只是不確定如何填充表單上的隱藏字段。任何建議將不勝感激！

這裏的JS：

function getLocation(locationrouting) 
    { 
    var getLocation= newXMLHttpRequest(); // sending request 
    getLocation.open("GET", "/PP?PAGE=GETLOCATIONNAME&ROUTINGNUM=" + locationrouting, false); 
    getLocation.send(null); // getting location 

    var dv = document.getElementById("location_div"); 
    var verifyUnfound() 

    if (getlocation.responseText === 'LOCATION NOT FOUND') 
    { 
     dv.style.color = "red"; 
    } 
     else 
    { 
     dv.style.color = "black"; 
    } 
    dv.innerHTML = getLocation.responseText; 
    }

HTML：

<input type="hidden" id="someid" name="somename" value="somevalue"> 

JS：

var hiddenField = document.getElementById('someid'); 
hiddenField.value = <whatever>; 

則可以將功能更改爲：

function getLocation(locationrouting) { 
    var getLocation= newXMLHttpRequest(); // sending request 
    getLocation.open("GET", "/PP?PAGE=GETLOCATIONNAME&ROUTINGNUM=" + locationrouting, false); 
    getLocation.send(null); // getting location 

    var dv = document.getElementById("location_div"); 
    var verifyUnfound(); 
    var hiddenField = document.getElementById('someid'); 

    if (getlocation . responseText === 'LOCATION NOT FOUND') { 
     dv.style.color = "red"; 
    } else { 
     dv.style.color = "black"; 
    } 
    dv.innerHTML = getLocation . responseText; 
    hiddenField.value = getLocation . responseText; 
}

使用jQuery，它會設置值並更輕鬆地執行AJAX請求。

$("#something").attr("value", myvalue)
