如何设置动态选择的选项值?我已经尝试了相同的,
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName == "h")
{
Button btn = (Button)(e.CommandSource);
if(btn.Text == "hide")
{
btn.Text = "unhide";
//Do additional work here, when unhiding.
}
else
{
btn.Text = "hide";
//Do additional work here, when hiding.
}
}
}

试试这个:
function editFromDB(optionVal){
$.get("/myEnd",function(myData) {
var s = $('<select id="' + optVal + '" name="selectName" ></select>');
$(myData).each(function(iter,element){
var op = $('<option>');
...
if(elem.name == optVal)
op.attr('selected','selected');
s.append(op);
});
//$("#" + optVal).val(optVal);

只需添加&#34;选中:true&#34;
For i As Integer = 2 To 10
xlWorkSheet.Range("E" & i).Value = rNum.Next()
Next i
使用它的两种方法:
$('<option></option>', {
value:"lol2",
text: "yo2",
selected : true
}).appendTo($("#test"));
或者你可以这样做:
$(myData).each(function(iter, element){
if (your_condition_for_selected) {
$('<option></option>', {
value: elem.name,
text: elem.name,
selected : true
}).appendTo(s);
});
} else {
$('<option></option>', {
value: elem.name,
text: elem.name
}).appendTo(s);
});
}

首先,您需要将已创建的select
附加到DOM,然后才能在其上设置val()
。
其次,您可以直接使用s
变量中的jQuery对象,而无需将id
选择器混合在一起。试试这个:
function editFromDB(optVal) {
$.get("/myEnd", function(myData) {
var $s = $('<select id="' + optVal + '" name="selectName" ></select>').appendTo('body'); // append here as needed
$.each(myData, function(i, element){
$('<option></option>', {
value: elem.name,
text: elem.name
}).appendTo($s);
});
$s.val(optVal);
});
}
