js處理網(wǎng)頁編輯器轉義、去除轉義、去除HTML標簽的正則
富文本編輯器生成的HTML標簽,進行轉義,然后寫入數(shù)據(jù)庫,防止腳本注入:
function htmlEncode(value){ return $('<div/>').text(value).html(); }
1、從數(shù)據(jù)庫拿出的轉義后的HTML標簽內容,先得去除轉義,然后再去除HTML標簽,是生成縮略文字。
/*移除HTML標簽代碼*/ function removeHTMLTag(str) { str = str.replace(/<\/?[^>]*>/g,''); //去除HTML tag str = str.replace(/[ | ]*\n/g,'\n'); //去除行尾空白 //str = str.replace(/\n[\s| | ]*\r/g,'\n'); //去除多余空行 str=str.replace(/ /ig,'');//去掉 return str; } //轉意符換成普通字符 function escape2Html(str) { var arrEntities={'lt':'<','gt':'>','nbsp':' ','amp':'&','quot':'"'}; return str.replace(/&(lt|gt|nbsp|amp|quot);/ig,function(all,t){return arrEntities[t];}); }
如果是文章詳情頁的話,直接去除轉義就可以顯示在頁面了:
//轉意符換成普通字符 function escape2Html(str) { var arrEntities={'lt':'<','gt':'>','nbsp':' ','amp':'&','quot':'"'}; return str.replace(/&(lt|gt|nbsp|amp|quot);/ig,function(all,t){return arrEntities[t];}); }
2、JS正則過濾(去除)富文本編輯器中的FONT-SIZE標簽
var test=test.replace(/font-size:\w+;?/g,'');
3、js處理去掉富文本編輯的html,樣式,只顯示純文字內容,以供列表頁使用

console.log(description) </script>
4、jQuery JavaScript正則表達式與\n代替<BR>
Lee TaylorTeneff給出了該問題的處理方式:
var str = document.getElementById('mydiv').innerHTML;
document.getElementById('mytextarea').innerHTML = str.replace(/<br\s*[\/]?>/gi, "\n");
or using jQuery:
var str = $("#mydiv").html();
var regex = /<br\s*[\/]?>/gi;
$("#mydiv").html(str.replace(regex, "\n"));
5、要去除html標簽,圖片,換行,回車等
description = description.replace(/(\n)/g, ""); description = description.replace(/(\t)/g, ""); description = description.replace(/(\r)/g, ""); description = description.replace(/<\/?[^>]*>/g, ""); description = description.replace(/\s*/g, "");
6、腳本之家小編寫的一個替換fackeditor中的多余br與空行的
//加強替換主要是考慮多個br的問題 function doRepAdvance(s){ var str=s.replace(/<p><br type="_moz"><\/p>/ig,""); str=str.replace(/<br type="_moz">\n <\/p>/ig, "</p>"); str=str.replace(/<br type="_moz">\n<\/p>/ig, "</p>"); str=str.replace(/<br type="_moz">\n\r<\/p>/ig, "</p>"); str=str.replace(/<br type="_moz"><\/p>/ig,"</p>"); str=str.replace(/<br \/>\n <\/p>/ig, "</p>"); str=str.replace(/<br>\n <\/p>/ig, "</p>"); str=str.replace(/<br \/>\n<\/p>/ig, "</p>"); str=str.replace(/<br \/>\n\r<\/p>/ig, "</p>"); str=str.replace(/(<br>\n){1,}<\/p>/ig,"</p>"); str=str.replace(/(<br>){1,}<\/p>/ig,"</p>"); str=str.replace(/<br>\n<\/p>/ig, "</p>"); str=str.replace(/<br><\/p>/ig,"</p>"); str=str.replace(/<p> <\/p>/ig,""); str=str.replace(/<p> <\/p>/ig,""); str=str.replace(/<p> <\/p>/ig,""); str=str.replace(/<p><\/p>/ig,""); return str; }
