我正在尝试这样做,当用户至少选中一个框时,图标必须显示,如果没有,它会隐藏。
使用我的代码,当我选择#master
复选框时,图标会显示,但是当我选择other checkbox
每一行的显示时,它不会显示。
为什么会这样?
HTML:
<table id="users-table" class="table table-hover table-condensed" style="width:100%">
<thead>
<tr>
<th><input type="checkbox" id="master"></th>
<th>Category</th>
<th>Description</th>
<th>Number of Items</th>
<th>Action</th>
</tr>
</thead>
</table>
<script type="text/javascript">
$(document).ready(function() {
oTable = $('#users-table').DataTable({
"processing": true,
"serverSide": true,
"bProcessing":false,
"bSort":false,
"ajax": "{{ route('datatable.getcategories') }}",
"columns": [
{data: 'checkbox', name: 'checkbox', orderable: false, searchable: false},
{data: 'name', name: 'name'},
{data: 'action', name: 'action', orderable: false, searchable: false}
],
});
});
</script>
控制器:
$stduents= Student::all();
return Datatables::of($student)->addColumn('checkbox', function ($std) {
return '<input type="checkbox" class="sub_chk" data-id="'.$std->id.'">';
})->make(true);
我在哪里选择我的复选框:
<script type="text/javascript">
$(document).ready(function () {
$("i[type='icon']").css('display','none'); //set style explicitly
$('#master').on('click', function(e) {
if($(this).is(':checked',true))
{
$(".sub_chk").prop('checked', true);
} else {
$(".sub_chk").prop('checked',false);
}
});
$('.delete_all').on('click', function(e) {
var allVals = [];
$(".sub_chk:checked").each(function() {
allVals.push($(this).attr('data-id'));
});
if(allVals.length <=0)
{
alert("Please select row.");
}
else {
var check = confirm("Are you sure you want to delete this row?");
if(check == true){
var join_selected_values = allVals.join(",");
$.ajax({
url: $(this).data('url'),
type: 'GET',
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
data: 'ids='+join_selected_values,
success: function (data) {
if (data['success'])
{
$("#" + data['tr']).slideUp("slow");
location.reload();
alert(data['success']);
}
else if (data['error'])
{
alert(data['error']);
}
else
{
//alert('Whoops Something went wrong!!');
}
},
error: function (data) {
alert(data.responseText);
}
});
$.each(allVals, function( index, value )
{
$('table tr').filter("[data-row-id='" + value + "']").remove();
});
}
}
});
$('[data-toggle=confirmation]').confirmation({
rootSelector: '[data-toggle=confirmation]',
onConfirm: function (event, element) {
element.trigger('confirm');
}
});
$(document).on('confirm', function (e) {
var ele = e.target;
e.preventDefault();
$.ajax({
url: ele.href,
type: 'GET',
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
success: function (data) {
if (data['success'])
{
$("#" + data['tr']).slideUp("slow");
location.reload();
alert(data['success']);
}
else if (data['error']) {
alert(data['error']);
}
else
{
alert('Whoops Something went wrong!!');
}
},
error: function (data) {
alert(data.responseText);
}
});
return false;
});
});
</script>
至少选中一个复选框时显示图标:
<script>
$("input[type='checkbox']").click(function() {
var atLeastOneChecked = false;
$("input[type='checkbox']").each(function(index) {
if ($(this).prop('checked'))
atLeastOneChecked = true;
});
if (atLeastOneChecked) {
$("i[type='icon']").show(); //built-in jquery function
//...or...
$("i[type='icon']").css('display','inline-block'); //or set style explicitly
} else {
$("i[type='icon']").hide(); //built-in jquery function
//...or...
$("i[type='icon']").css('display','none'); //set style explicitly
}
});
</script>
由于您的复选框是在页面加载后添加的,因此$("input[type='checkbox']").click(...)
不会向其中添加事件处理程序。IE
//will handle clicked events on checkbox existing when this js runs
$('input[type="checkbox"]').click(function() {
alert('clicked')
});
//will handle clicked events on dynamically added checkboxes
$(document).on('click', 'input[type="checkbox"]', function() {
alert('clicked2');
});
//add new checkbox to page
$('button').click(function() { $('#master').after($('<input type="checkbox" >')) });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input type="checkbox" id="master">
<button type='button'>Add Checkbox</button>
你想要做的是 $(document).on('click', 'input[type="checkbox"]', function() { ... }
