使用jQuery,如何动态设置选择框的大小属性?
我想将其包含在此代码中:
$("#mySelect").bind("click",
function() {
$("#myOtherSelect").children().remove();
var options = '' ;
for (var i = 0; i < myArray[this.value].length; i++) {
options += '<option value="' + myArray[this.value][i] + '">' + myArray[this.value][i] + '</option>';
}
$("#myOtherSelect").html(options).attr [... use myArray[this.value].length here ...];
});
});

哎呀,这是
$('#mySelect').attr('size', value)
答案 1 :(得分:1)
$("#mySelect").bind("click", function(){
$("#myOtherSelect").children().remove();
var myArray = [ "value1", "value2", "value3" ];
for (var i = 0; i < myArray.length; i++) {
$("#myOtherSelect").append( '<option value="' + myArray[i] + '">' + myArray[i] + '</option>' );
}
$("#myOtherSelect").attr( "size", myArray.length );
});
