我正在使用bootstrap-multiselect通过两个关键菜单为用户提供出色的控制器。我的第一个菜单名为groups
,另一个名为queues
。队列中的每个选项都有一个HTML5数据属性(即data-group =" X",其中X是一个组值)
当用户从groups
菜单中选择一个选项/组时,我想查找并隐藏queues
菜单中data-group
不等于所选的.show()
菜单中的每个队列/选项组菜单中的组。
在确定需要隐藏/显示的队列/项目后,我尝试使用.hide()
和.addClass('hidden')
扩展名。然后我尝试使用.removeClass('hidden')
和$(function () {
var queueGroupIds = $('#QueueGroupIds');
var queueIds = $('#QueueIds');
queueGroupIds.multiselect({
nonSelectedText: 'Select group(s)',
onChange: function (option, checked, select) {
var groups = queueGroupIds.find('option:selected');
if (groups.length == 0) {
//When none of the groups are selected, show all queues!
queueIds.find('option').each(function (i, q) {
$(q).show();
});
}
var queueToDeselect = [];
//loop over every select option "if any are selected"
groups.each(function (index, grp) {
var group = $(grp);
// loop over every queue option
queueIds.find('option').each(function (i, q) {
var queue = $(q);
//id the data-group value == selected group show the item
if (queue.data('group') == group.val()) {
queue.show();
//this prints the value which should be showing
console.log('showing', queue.val());
} else {
queueToDeselect.push(queue.val());
queue.hide();
//this prints the value which should be hidden
console.log('hidding', queue.val());
}
});
});
//Delected all hidden queues
queueIds.multiselect('deselect', queueToDeselect);
queueIds.multiselect('refresh');
}
});
queueIds.multiselect({
nonSelectedText: 'Select queue(s)'
});
});
方法,但没有任何方法可以帮助我。
如何使用bootstrap-multiselect动态显示/隐藏项目?
这是我的代码
summary_hook = tf.train.SummarySaverHook(
save_secs=2,
output_dir=MODEL_DIR,
summary_op=tf.summary.merge_all())
# ...
classifier.train(
input_fn,
steps=1000,
hooks=[summary_hook])

无需任何手动凌乱的DOM ADD / REMOVE操作。 Multiselect将继承您放在原始列表中的禁用类,因此您只需在设置禁用值并刷新列表后使用css将其作为目标。让多选担心dom操纵。
示例HTML:
Note
Jquery的:
<select id="one" multiple="multiple">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<select id="two" multiple="multiple">
<option data-group="1" value="OneA" disabled >One A</option>
<option data-group="1" value="OneB" disabled>One B</option>
<option data-group="2" value="TwoA" disabled>Two A</option>
<option data-group="2" value="TwoB" disabled>Two B</option>
<option data-group="3" value="ThreeA" disabled >Three A</option>
</select>
只是一小撮CSS:
$(document).ready(function() {
$('#one').multiselect({
onChange: function(element, checked) {
var opts = $('*[data-group="'+ element.val() +'"]');
if (checked === true) {
opts.prop('disabled', false).prop('selected', false);
}
else if (checked === false) {
opts.prop('disabled', true).prop('selected', false);
}
$("#two").multiselect('refresh');
}
});
$('#two').multiselect();
});

//Because we alter the DOM, we need to save an instance of the original list
//There are many ways to do this, I chose an easy one
var globalClone = $('#queues option');
//Init the queues
$('#queues').multiselect({
nonSelectedText: 'Select queue(s)',
onChange: function (option, checked, select) {
}
});
//Init the groups
$('#groups').multiselect({
nonSelectedText: 'Select group(s)',
onChange: function (option, checked, select) {
//Store the list of selections in an array
var selections = $('#groups').val();
//Reset the queue to it's starting list so we can loop
$('#queues').html(globalClone);
//Look at each option
$('#queues option').each(function(){
//"includes" may not be widly suppoerted but there are other ways to see if a value is in an array
//Check to see if the data-group value is in the selections array, if it's not
if( selections.includes(String($(this).data('group'))) == false ){
//Remove the option from the DOM
$(this).remove();
}
});
//Rebuild, per the multiselect docs basically reinit the select. Nice we don't have to destroy and recreate.
$('#queues').multiselect('rebuild');
}
});
这不是我如何准确地保留生产代码,而是告诉您它是如何工作的。
基本上,循环,检查,改变DOM,并重建多选。我想这就是你想要的。
