有没有输入3个字符后才开始搜索的选项?
我为显示 20,000 个条目的同事编写了一个 PHP 脚本,他们提示说,在输入单词时,前几个字母会导致所有内容卡住。
另一种方法是通过单击按钮而不是通过字符输入来开始搜索。
下面是我当前的代码:
$("#my_table").dataTable( {
"bJQueryUI": true,
"sPaginationType": "full_numbers",
"bAutoWidth": false,
"aoColumns": [
/* qdatetime */ { "bSearchable": false },
/* id */ null,
/* name */ null,
/* category */ null,
/* appsversion */ null,
/* osversion */ null,
/* details */ { "bVisible": false },
/* devinfo */ { "bVisible": false, "bSortable": false }
],
"oLanguage": {
"sProcessing": "Wait please...",
"sZeroRecords": "No ids found.",
"sInfo": "Ids from _START_ to _END_ of _TOTAL_ total",
"sInfoEmpty": "Ids from 0 to 0 of 0 total",
"sInfoFiltered": "(filtered from _MAX_ total)",
"sInfoPostFix": "",
"sSearch": "Search:",
"sUrl": "",
"oPaginate": {
"sFirst": "<<",
"sLast": ">>",
"sNext": ">",
"sPrevious": "<"
},
"sLengthMenu": 'Display <select>' +
'<option value="10">10</option>' +
'<option value="20">20</option>' +
'<option value="50">50</option>' +
'<option value="100">100</option>' +
'<option value="-1">all</option>' +
'</select> ids'
}
} );
最佳答案
版本 1.10 的解决方案 -
在此处寻找完整答案但没有找到之后,我写了这篇文章(利用文档中的代码,以及此处的一些答案)。
下面的代码用于延迟搜索,直到至少输入 3 个字符:
// Call datatables, and return the API to the variable for use in our code
// Binds datatables to all elements with a class of datatable
var dtable = $(".datatable").dataTable().api();
// Grab the datatables input box and alter how it is bound to events
$(".dataTables_filter input")
.unbind() // Unbind previous default bindings
.bind("input", function(e) { // Bind our desired behavior
// If the length is 3 or more characters, or the user pressed ENTER, search
if(this.value.length >= 3 || e.keyCode == 13) {
// Call the API search function
dtable.search(this.value).draw();
}
// Ensure we clear the search if they backspace far enough
if(this.value == "") {
dtable.search("").draw();
}
return;
});
