Question

我是Ajax的新手。我想在服务器上使用responseText填充表单上的隐藏字段。我能够在HTML中将responseText显示为innerHTML。我只是不确定如何填充表单上的隐藏字段。任何建议将不胜感激！

这是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>;

您可以将功能更改为：

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，它将设置值并更容易地执行AJAX请求。

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