RegExp - replace the `html` tags on search and highlight

Question

I am doing a search and highlight process using regex , the problem i am facing is, it's accounts the html tags too search option.

since the html element replaces, i am getting bad result. how to avoid this?

here is my patter to search and replace the html text to mark tag.

 var src_str = $("#test").html(); var origional = $("#backup").html(); var searchIt = function (text) { console.log(text); var marks = text; marks = marks.replace(/(\\s+)/,"(<[^>]+>)*$1(<[^>]+>)*"); var pattern = new RegExp("("+marks+")", "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); } var resetIt = function (Text) { $("#parent").html(origional); if(!Text.length) return; searchIt(Text); } $('#keyWord').keyup(function (e){ var inputText = $.trim($(e.target).val()); resetIt(inputText); });

Answer 1

So it seems like your problem is that you're inserting <mark>...</mark> tags around your search results to highlight them and later matches can't match around these as well?

I was able to get it working like this:

 var src_str = $("#test").html(); var origional = $("#backup").html(); var searchIt = function (text) { console.log(text); var marks = text; marks = marks.replace(/(\\s+)/,"(<[^>]+>)*$1(<[^>]+>)*"); var pattern = new RegExp("("+marks+"+(?=[^>]*(?:<|\\Z)))", "gi"); src_str = src_str.replace(/<\\/?mark.*?>/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); } var resetIt = function (Text) { $("#parent").html(origional); if(!Text.length) return; searchIt(Text); } $('#keyWord').keyup(function (e){ var inputText = $.trim($(e.target).val()); resetIt(inputText); });
