在jQuery中search和突出显示

我想使用jQuery / Java Script来search和突出显示文本。

示例HTML 1：

<div id="div1"><b>Good</b> <b>Morning</b> </div> <div id="div2">Good Evening</div> <div id="div3">Good Morning</div>Searched String = "Good Morning" 

当我searchstring“早上好”时，div1和div3中的内容应该突出显示。 即。 输出的html应该是

 <div id="div1"><span class="highlight"><b>Good</b> <b>Morning</b> </span></div> <div id="div2">Good Evening</div> <div id="div3"><span class="highlight">Good Morning</span></div> 

我已经使用插件https://raw.github.com/bartaz/sandbox.js/master/jquery.highlight.js将search到的内容包含在span中。 但只有div3被突出显示。 请帮忙。

  var src_str = $("#test").text(); var term = "my text"; term = term.replace(/(\s+)/,"(<[^>]+>)*$1(<[^>]+>)*"); var pattern = new RegExp("("+term+")", "gi"); src_str = src_str.replace(pattern, "<mark>$1</mark>"); src_str = src_str.replace(/(<mark>[^<>]*)((<[^>]+>)+)([^<>]*<\/mark>)/,"$1</mark>$2<mark>$4"); $("#test").html(src_str);

脚本

 jQuery.fn.highlight = function(pat) { function innerHighlight(node, pat) { var skip = 0; if (node.nodeType == 3) { var pos = node.data.toUpperCase().indexOf(pat); if (pos >= 0) { var spannode = document.createElement('span'); spannode.className = 'highlight'; var middlebit = node.splitText(pos); var endbit = middlebit.splitText(pat.length); var middleclone = middlebit.cloneNode(true); spannode.appendChild(middleclone); middlebit.parentNode.replaceChild(spannode, middlebit); skip = 1; } } else if (node.nodeType == 1 && node.childNodes && !/(script|style)/i.test(node.tagName)) { for (var i = 0; i < node.childNodes.length; ++i) { i += innerHighlight(node.childNodes[i], pat); } } return skip; } return this.each(function() { innerHighlight(this, pat.toUpperCase()); }); }; jQuery.fn.removeHighlight = function() { function newNormalize(node) { for (var i = 0, children = node.childNodes, nodeCount = children.length; i < nodeCount; i++) { var child = children[i]; if (child.nodeType == 1) { newNormalize(child); continue; } if (child.nodeType != 3) { continue; } var next = child.nextSibling; if (next == null || next.nodeType != 3) { continue; } var combined_text = child.nodeValue + next.nodeValue; new_node = node.ownerDocument.createTextNode(combined_text); node.insertBefore(new_node, child); node.removeChild(child); node.removeChild(next); i--; nodeCount--; } } return this.find("span.highlight").each(function() { var thisParent = this.parentNode; thisParent.replaceChild(this.firstChild, this); newNormalize(thisParent); }).end(); };

试试这个： – http://jsfiddle.net/adiioo7/H7CqV/

您需要从div1删除b标签，并且为了应用粗体属性，您可以使用css属性font-weight:bold 。

HTML： –

 <div id="div1" style="font-weight:bold">Good Morning</div> <div id="div2">Good Evening</div> <div id="div3">Good Morning</div> 

要么

 <div id="div1"><b>Good Morning</b></div> <div id="div2">Good Evening</div> <div id="div3">Good Morning</div> 

JS： –

 $("body").highlight("Good Morning");
