Jquery从下拉列表中删除项目
问题描述:
jQuery(document).ready(function () {
$lstAccountType = $('select[id*="account_type"]');
$lstAccountType.change(function () {
$(this).remove('option[text="select one"]')
});
});
我想删除点击下拉列表中的第一个元素。有人有任何指针吗?
I want to remove the first element in my dropdown list when it is clicked. Does anyone have any pointers in regards to this?
答
你应该可以使用:
$lstAccountType.change(function () {
$lstAccountType.find("option[value='"+$lstAccountType.val()+"']").remove();
});
我还没有测试过这个,但是去看看,如果有什么好处,不是?
I haven't tested this, but have a go and let me know if it is any good or not?

如果您只想删除第一个选项时间可以尝试:
If you only want to remove the first option each time you could try:
$lstAccountType.change(function () {
if ($lstAccountType.find("option:first").attr("value") == $lstAccountType.val()) {
$lstAccountType.find("option[value='"+$lstAccountType.val()+"']").remove();
}
});
需要一些整理,但希望可能有所帮助。
It needs some tidying up, but hopefully that might help.

如果您只想删除第一个选项,可以执行以下操作:
If you want to remove the first option only once you could do:
var first_option_removed = false;
$lstAccountType.change(function () {
if (!first_option_removed) {
if ($lstAccountType.find("option:first").attr("value") == $lstAccountType.val()) {
$lstAccountType.find("option[value='"+$lstAccountType.val()+"']").remove();
first_option_removed = true;
}
}
});
