我已经开始将 DataTables 插件（v1.6.2）用于 jQuery （v1.4.2），我想问你是否知道 设置 或插件，可让我突出显示已过滤行中搜索文本框中使用的文字。
提前谢谢

我必须建议highlight plugin：）
我现在在同一场景中使用它，到目前为止我没有遇到任何问题。
用法非常简单：
$("#myTable").highlight($("#searchBox").val());
只需将高亮的CSS类放在您想要的样式表样式中即可：
.highlight { background-color: yellow }

您可以通过复制此内容来使用此功能：
jQuery.fn.dataTableExt.oApi.fnSearchHighlighting = function(oSettings) {
oSettings.oPreviousSearch.oSearchCaches = {};
oSettings.oApi._fnCallbackReg( oSettings, 'aoRowCallback', function( nRow, aData, iDisplayIndex, iDisplayIndexFull) {
// Initialize search string array
var searchStrings = [];
var oApi = this.oApi;
var cache = oSettings.oPreviousSearch.oSearchCaches;
// Global search string
// If there is a global search string, add it to the search string array
if (oSettings.oPreviousSearch.sSearch) {
searchStrings.push(oSettings.oPreviousSearch.sSearch);
}
// Individual column search option object
// If there are individual column search strings, add them to the search string array
if ((oSettings.aoPreSearchCols) && (oSettings.aoPreSearchCols.length > 0)) {
for (var i in oSettings.aoPreSearchCols) {
if (oSettings.aoPreSearchCols[i].sSearch) {
searchStrings.push(oSettings.aoPreSearchCols[i].sSearch);
}
}
}
// Create the regex built from one or more search string and cache as necessary
if (searchStrings.length > 0) {
var sSregex = searchStrings.join("|");
if (!cache[sSregex]) {
var regRules = "("
, regRulesSplit = sSregex.split(' ');
regRules += "("+ sSregex +")";
for(var i=0; i<regRulesSplit.length; i++) {
regRules += "|("+ regRulesSplit[i] +")";
}
regRules += ")";
// This regex will avoid in HTML matches
cache[sSregex] = new RegExp(regRules+"(?!([^<]+)?>)", 'ig');
}
var regex = cache[sSregex];
}
// Loop through the rows/fields for matches
jQuery('td', nRow).each( function(i) {
// Take into account that ColVis may be in use
var j = oApi._fnVisibleToColumnIndex( oSettings,i);
// Only try to highlight if the cell is not empty or null
if (aData[j]) {
// If there is a search string try to match
if ((typeof sSregex !== 'undefined') && (sSregex)) {
this.innerHTML = aData[j].replace( regex, function(matched) {
return "<span class='filterMatches'>"+matched+"</span>";
});
}
// Otherwise reset to a clean string
else {
this.innerHTML = aData[j];
}
}
});
return nRow;
}, 'row-highlight');
return this;
};
内部：
dataTables.search-highlight.js
就像这个例子一样召唤：
<script type="text/javascript" src="jquery.dataTables.js"></script>
<script type="text/javascript" src="dataTables.search-highlight.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var oTable = $('#example').dataTable();
oTable.fnSearchHighlighting();
} );
</script>
并将此代码添加到css文件中：
.filterMatches{
background-color: #BFFF00;
}

我知道这个问题已经超过6年了，这里的答案可能会帮助你。但对于仍在搜索此内容的用户，有一个新插件可将mark.js（JavaScript关键字荧光笔）整合到DataTables中：datatables.mark.js。
用法很简单：
$("table").DataTables({
mark: true
});
以下是一个示例：https://jsfiddle.net/julmot/buh9h2r8/
这是最干净的方式，也为您提供了任何给定解决方案都无法提供的选项。
现在有官方DataTables blog article可用。

您可以使用以下添加
jQuery.fn.dataTableExt.oApi.fnSearchHighlighting = function(oSettings) {
// Initialize regex cache
oSettings.oPreviousSearch.oSearchCaches = {};
oSettings.oApi._fnCallbackReg( oSettings, 'aoRowCallback', function( nRow, aData, iDisplayIndex, iDisplayIndexFull) {
// Initialize search string array
var searchStrings = [];
var oApi = this.oApi;
var cache = oSettings.oPreviousSearch.oSearchCaches;
// Global search string
// If there is a global search string, add it to the search string array
if (oSettings.oPreviousSearch.sSearch) {
searchStrings.push(oSettings.oPreviousSearch.sSearch);
}
// Individual column search option object
// If there are individual column search strings, add them to the search string array
// searchTxt=($('#filter_input input[type="text"]')?$('#filter_input input[type="text"]').val():"");
var searchTxt = $('input[type="search"]').val();
// console.log("txt" + searchTxt);
if ((oSettings.aoPreSearchCols) && (oSettings.aoPreSearchCols.length > 0)) {
for (var i in oSettings.aoPreSearchCols) {
if (oSettings.aoPreSearchCols[i].sSearch) {
searchStrings.push(searchTxt);
}
}
}
// Create the regex built from one or more search string and cache as necessary
/*if (searchStrings.length > 0) {
var sSregex = searchStrings.join("|");
if (!cache[sSregex]) {
// This regex will avoid in HTML matches
cache[sSregex] = new RegExp("("+escapeRegExpSpecialChars(sSregex)+")(?!([^<]+)?>)", 'i');
}
var regex = cache[sSregex];
}*/
if (searchStrings.length > 0) {
var sSregex = searchStrings.join("|");
if (!cache[sSregex]) {
var regRules = "("
, regRulesSplit = sSregex.split(' ');
regRules += "("+ sSregex +")";
for(var i=0; i<regRulesSplit.length; i++) {
regRules += "|("+ regRulesSplit[i] +")";
}
regRules += ")";
// This regex will avoid in HTML matches
cache[sSregex] = new RegExp(regRules+"(?!([^<]+)?>)", 'ig');
}
var regex = cache[sSregex];
}
// Loop through the rows/fields for matches
jQuery('td', nRow).each( function(i) {
// Take into account that ColVis may be in use
var j = oApi._fnVisibleToColumnIndex( oSettings,i);
// Only try to highlight if the cell is not empty or null
// console.log("data "+ aData[j] + " j " + j);
// console.log("data 1 "+ nRow);
if (aData) {
// If there is a search string try to match
if ((typeof sSregex !== 'undefined') && (sSregex)) {
//console.log("here :: "+$(this).text());
this.innerHTML = $(this).text().replace( regex, function(matched) {
return "<span class='filterMatches'>"+matched+"</span>";
});
}
// Otherwise reset to a clean string
else {
this.innerHTML = $(this).text();//aData[j];
}
}
});
return nRow;
}, 'row-highlight');
return this;
};
这个解决方案对我有用。 注意：目前它不支持单个列过滤，但您只需在代码中取消注释。
searchTxt=($('#filter_input input[type="text"]')?$('#filter_input input[type="text"]').val():"");
我已经使用datatables 1.10.2和jquery 1.9.2版本对此进行了测试。

此附加功能具有突出显示搜索文本的更好功能。如果您在对话框中创建了数据表，那么在对话框重新打开时，您需要重新初始化数据表。
在DatatableHighlighter.js
中jQuery.fn.dataTableExt.oApi.fnSearchHighlighting = function(oSettings) {
// Initialize regex cache
oSettings.oPreviousSearch.oSearchCaches = {};
oSettings.oApi._fnCallbackReg( oSettings, 'aoRowCallback', function( nRow, aData, iDisplayIndex, iDisplayIndexFull) {
// Initialize search string array
var searchStrings = [];
var oApi = this.oApi;
var cache = oSettings.oPreviousSearch.oSearchCaches;
// Global search string
// If there is a global search string, add it to the search string array
if (oSettings.oPreviousSearch.sSearch) {
searchStrings.push(oSettings.oPreviousSearch.sSearch);
}
// Individual column search option object
// If there are individual column search strings, add them to the search string array
// searchTxt=($('#filter_input input[type="text"]')?$('#filter_input input[type="text"]').val():"");
var searchTxt = $('input[type="search"]').val();
// console.log("txt" + searchTxt);
if ((oSettings.aoPreSearchCols) && (oSettings.aoPreSearchCols.length > 0)) {
for (var i in oSettings.aoPreSearchCols) {
if (oSettings.aoPreSearchCols[i].sSearch) {
searchStrings.push(searchTxt);
}
}
}
// Create the regex built from one or more search string and cache as necessary
if (searchStrings.length > 0) {
var sSregex = searchStrings.join("|");
if (!cache[sSregex]) {
var regRules = "("
, regRulesSplit = sSregex.split(' ');
regRules += "("+ sSregex +")";
for(var i=0; i<regRulesSplit.length; i++) {
regRules += "|("+ regRulesSplit[i] +")";
}
regRules += ")";
// This regex will avoid in HTML matches
cache[sSregex] = new RegExp(regRules+"(?!([^<]+)?>)", 'ig');
//cache[sSregex] = new RegExp(regRules+"", 'ig');
}
var regex = cache[sSregex];
}
// Loop through the rows/fields for matches
jQuery('td', nRow).each( function(i) {
// Take into account that ColVis may be in use
var j = oApi._fnVisibleToColumnIndex( oSettings,i);
if (aData) {
// If there is a search string try to match
if ((typeof sSregex !== 'undefined') && (sSregex)) {
//For removing previous added <span class='filterMatches'>
var element = $(this);//convert string to JQuery element
element.find("span").each(function(index) {
var text = $(this).text();//get span content
$(this).replaceWith(text);//replace all span with just content
}).remove();
var newString = element.html();//get back new string
this.innerHTML = newString.replace( regex, function(matched) {
return "<span class='filterMatches'>"+matched+"</span>";
});
}
// Otherwise reset to a clean string
else {
//For removing previous added <span class='filterMatches'>
var element = $(this);//convert string to JQuery element
element.find("span").each(function(index) {
var text = $(this).text();//get span content
$(this).replaceWith(text);//replace all span with just content
}).remove();
var newString = element.html();
this.innerHTML = newString;//$(this).html()//$(this).text();
}
}
});
return nRow;
}, 'row-highlight');
return this;
};
并称之为......
$("#button").click(function() {
dTable = $('#infoTable').dataTable({"bPaginate": false,"bInfo" : false,"bFilter": true,"bSort":false, "autoWidth": false,"destroy": true,
"columnDefs": [
{ "width": "35%", "targets": 0 },
{ "width": "65%", "targets": 1 }
]});
$(".dataTables_filter input[type='search']").val('');
$("span[class='filterMatches']").contents().unwrap();
dTable.fnSearchHighlighting();
$("span[class='filterMatches']").contents().unwrap();
$("#AboutDialog").dialog('open');
});
