set value of input
提问by JP Hellemons
Sometimes code says more then words, so the following lines work:
有时代码会说更多的话，所以以下几行工作：
$("#text11").append($(xml).find("address").find("street"));
$("#<%= tbWoonplaats.ClientID %>").val('testing?');
but these do not:
但这些没有：
var street = $(xml).find("address").find("street");
$("#<%= tbAdres.ClientID %>").val(street);
it displays [object object] in the input
now i've tried to replace .val(street);with .val(new string(street));but that doesn't work either
它在输入中显示 [object object] 现在我已经尝试替换为.val(street);，.val(new string(street));但这也不起作用
appending to a span works but setting with .val()to input doesn't...
附加到跨度有效但设置.val()为输入不...
<span id="text11"></span>
EDITthe output of
编辑输出
var street = $(xml).find("address").find("street");
window.alert(street);
is: [object Object]
是：[对象对象]

Try this:
尝试这个：
var street = $(xml).find("address").find("street").text();
You were getting the node with .find("street"), but not its content, so you needed .text().
您使用 获取节点.find("street")，但未获取其内容，因此您需要.text().
EDIT:
编辑：
You can check to see if a streetnode was found using the lengthproperty.
您可以street使用该length属性检查是否找到了节点。
var street = $(xml).find("address").find("street");
alert(street.length); // should alert at least 1 if the find was successful
