我有select
框并添加更多button
。当我点击添加更多button
时,它会使用克隆创建另一个select
。在第一个选择框select
option
框中的select
值意味着应从下一个创建的select
框中删除该值。同时在选择框中选择当前value
框中显示的当前select
的值。正在动态加载选择框值。
例如:
<select name="section" id="section_1" class="sectionType">
<option value=" ">------</option>
<option value="05">test1</option>
<option value="06">test2</option>
<option value="07">test3</option>
<option value="08">test4</option>
<option value="10">test5</option>
<option value="11">test6</option>
<option value="12">test7</option>
<option value="13">test8</option>
<option value="14">test9</option>
</select>

这是你要找的吗?
我建议您使用index()
进行游戏和操作,这不会打扰您的动态值。
//Take a clone of last
var cloneElement = $('.sectionType:last').clone();
//Get index of option selected from last
var indexToRemove = $('.sectionType:last').find('option:selected').index();
//Remove previously selected index
cloneElement.find('option').eq(indexToRemove).remove();
//Change the id of an element
cloneElement.attr("id", "section_"+parseInt($('.sectionType').length+1));
//If element has options
if(cloneElement.find('option').length)
{
//Finally append it
$('body').append("<br/><br/>").append(cloneElement);
}
$('button').click(function(){
//Take a clone of last
var cloneElement = $('.sectionType:last').clone();
//Get index of option selected from last
var indexToRemove = $('.sectionType:last').find('option:selected').index();
//Remove previously selected index
cloneElement.find('option').eq(indexToRemove).remove();
//Change the id of an element
cloneElement.attr("id", "section_"+parseInt($('.sectionType').length+1));
//If element has options
if(cloneElement.find('option').length)
{
//Finally append it
$('body').append("<br/><br/>").append(cloneElement);
}
});

你可以这样试试。
$("#yourId").val(" ")//if your value has white spec else use like below line
$("#YourId").val("")//What ever you want to be selected, place your value in .val()

我希望这会对你有所帮助,如果你需要什么请问!
$("button").on("click", function() {
$("#section_1")
.clone()
.attr("id", "section_2")
.on("change", function() {
var sec2Val = $(this).val();
var delOption = $("#section_1 > option[value=" + sec2Val + "]").detach();
optionHolder.push(delOption);
})
.insertAfter($("#section_1"));
$(this).attr("disabled", "disabled");
});
var optionHolder = [];
$("#section_1").on("change", function() {
var sec1Val = $(this).val();
if ($("#section_2")) {
var delOption = $("#section_2 > option[value=" + sec1Val + "]").detach();
optionHolder.push(delOption);
}
});
