jquery select remove option
提问by Adam
I'm currently using this successfully to remove an option
我目前正在成功地使用它来删除一个选项
$("select#select_gender option[value='initial']").remove();
Is there a way remove an option without adding to the selector - like below?
有没有办法在不添加到选择器的情况下删除选项 - 如下所示？
$('select#select_gender').val('initial').remove();
thx
谢谢

$("select#select_gender option").filter("[value='initial']").remove();
I believe that does it.
我相信这样做。
or per your latest comment:
或根据您的最新评论：
var sel = $("select#select_gender");
sel.find("option[value='initial']").remove();

You could use something like this:
你可以使用这样的东西：
$("#select_gender").children().filter(function(index, option) {
return option.value==="initial";
}).remove();
If you wanted, you could turn it into a plugin, like so:
如果你愿意，你可以把它变成一个插件，像这样：
;(function($) {
$.fn.option=function(value) {
return this.children().filter(function(index, option) {
return option.value===value;
});
};
})(jQuery);
Then you could use this:
然后你可以使用这个：
$("#select_gender").option("initial").remove();
You can demo it here.
你可以在这里演示。

I suppose you can restrict it down to the option tags
我想您可以将其限制为选项标签
$("select#select_genter option").find("[value='initial']").remove()
and then for diffenet vals
然后对于不同的 vals
var beg_string = "[value='",
end_string = "']",
while ( ) {
/* loop through a list of values */
$("select#select_genter option").find(beg_string + val + end_str).remove();
}

Why would you do it? You can do something like
你为什么要这样做？你可以做类似的事情
$('select#select_gender').each(function(a,b){
if ($(this).val() == 'initial'){
$(this).remove();
}
});
but I DO NOT RECOMMEND IT. Use that first one. It's perfect and easy
但我不推荐它。使用第一个。这是完美而简单的
