我在我的应用程序中使用Jquery数据表。我的表包含以下列：
1.Name 2.Position 3.Office 4.Age 5.Date and 6.Salary
在那里，我从表响应动态构建“Office”列的多选过滤器选项。我在以下JSFiddle链接中尝试了我的示例。
HTML代码：
<div class="row">
<div class="col s12">
<div class="card z-depth-3 hoverable">
<div class="card-title">
<div class="row" style="margin-bottom: 0;">
<div class="col s12 m4">
<h5>Summary</h5>
</div>
<div class="col s12 m3 right-align">
<span style="font-size:18px;font-weight:500;" multiple="true">Office: </span>
<select multiple="true" id="officeFltr">
</select>
</div>

<div class="card-action">

JS代码：
$(document).ready(function (){
var table = $('#example').DataTable({
dom: 'lrtip',
initComplete: function () {
this.api().columns([2]).every( function () {
var column = this;
console.log(column);
var select = $("#officeFltr");
column.data().unique().sort().each( function ( d, j ) {
select.append( '<option value="'+d+'">'+d+'</option>' )
} );
} );
$("#officeFltr").material_select();
}
});
$('#officeFltr').on('change', function(){
var search = [];
$.each($('#officeFltr option:selected'), function(){
search.push($(this).val());
});
search = search.join('|');
table.column(2).search(search, true, false).draw();
});
});
但是这个过滤器功能不起作用，因为它在选项中包含特殊的字符括号'（'＆amp;'）'。
我尝试了下面的动作线也禁用正则表达式。但这只适用于单一选项，而不适用于多种选项。
table.column(2).search(search, false, false).draw();
还有其他方法可以达到这个目的吗？
答案 0 :(得分：3)
问题在于括号()
为了正常工作，您必须添加反斜杠\
var escape_parenthesis = new RegExp( '(\\' + [ '(', ')'].join('|\\') + ')', 'g' );
search = search.replace( escape_parenthesis, '\\$1' );
答案 1 :(得分：2)
您可以为每个选择值设置Datatble escepe Regex util函数void Start()
{
SetProjectionMatrixAndFOV
}
void Update()
{
overlayCamera.transform.position = Camera.main.transform.position;
overlayCamera.transform.rotation = Camera.main.transform.rotation;
}
private void SetProjectionMatrixAndFOV()
{
overlayCamera.fieldOfView = Camera.main.fieldOfView;
overlayCamera.projectionMatrix = Camera.main.projectionMatrix;
}
：
$.fn.dataTable.util.escapeRegex()请参阅Fiddle
以下代码段：
var val;
$.each($('#officeFltr option:selected'), function(){
val = $.fn.dataTable.util.escapeRegex($(this).val());
search.push(val);
});
$(document).ready(function() {
var table = $('#example').DataTable({
dom: 'lrtip',
initComplete: function() {
this.api().columns([2]).every(function() {
var column = this;
console.log(column);
var select = $("#officeFltr");
column.data().unique().sort().each(function(d, j) {
select.append('<option value="' + d + '">' + d + '</option>')
});
});
$("#officeFltr").material_select();
}
});
$('#officeFltr').on('change', function() {
var search = [];
var val;
$.each($('#officeFltr option:selected'), function() {
val = $.fn.dataTable.util.escapeRegex($(this).val());
search.push(val);
});
search = search.join('|');
table.column(2).search(search, true, false).draw();
});
});
