使用jQuery作为JS对象向select中添加选项的最佳方法是什么? [英] What is the best way to add options to a select from as a JS object with jQuery?
问题描述
使用jQuery从JavaScript对象向< select>
添加选项的最佳方法是什么?
<我正在寻找一些我不需要插件的东西,但我也会对那里的插件感兴趣。
这是我做了什么:
selectValues = {1:test 1,2:test 2};
for(key in selectValues){
if(typeof(selectValues [key] =='string'){
$('#mySelect')。append('< ; option value ='+ key +'>'+ selectValues [key] +'< / option>');
}
}
干净/简单的解决方案:
这是一个清洁up and simplified matdumsa的版本:
$。each(selectValues,function(key,value) ){
$('#mySelect')
.append($('< option>',{value:key})
.text(value));
});
来自matdumsa的更改:(1)删除了append()中的选项的关闭标记(2)将属性/属性移动到地图中作为append()的第二个参数。
S ame作为其他答案,以jQuery方式:
$。each(selectValues,function(key,value){
$('#mySelect')
.append($(< option>< / option>)
.attr(value,key)
.text(value) );
});
What is the best method for adding options to a <select>
from a JavaScript object using jQuery?
I'm looking for something that I don't need a plugin to do, but I would also be interested in the plugins that are out there.
This is what I did:
selectValues = { "1": "test 1", "2": "test 2" };
for (key in selectValues) {
if (typeof (selectValues[key] == 'string') {
$('#mySelect').append('<option value="' + key + '">' + selectValues[key] + '</option>');
}
}
A clean/simple solution:
This is a cleaned up and simplified version of matdumsa's:
$.each(selectValues, function(key, value) {
$('#mySelect')
.append($('<option>', { value : key })
.text(value));
});
Changes from matdumsa's: (1) removed the close tag for the option inside append() and (2) moved the properties/attributes into an map as the second parameter of append().
Same as other answers, in jQuery fashion:
$.each(selectValues, function(key, value) {
$('#mySelect')
.append($("<option></option>")
.attr("value",key)
.text(value));
});
