问题 Essentially I want to undo the escapeHTML() function I found below, after I used it. function escapeHtml(unsafe) { return unsafe .replace(/&/g, "&") .replace(/</g, "<") .replace(/>/g, ">") .replace(/"/g, """) .replace(/'/g, "'"); } function unescapeHtml(safe) { return safe .replace("&", /&/g) .replace("<", /</g) .replace( ">", />/g) .replace(""", /"/g) .replace("'", /'/g); } var a = escapeHtml("<div> yo & yo squirrl's </div>"); var b = unescapeHtml(a); console.log(a); console.log(b);//should

问题 I want to call fn:replace inside EL inside c:out to replace quote caracters. The following does not work <c:out value="${fn:replace(userName,'"','\\"')}"/> because XML parser stops at first double quote and sees no c:cout tag termination (JSP compilation stage error). The following <c:out value="${fn:replace(userName,'"','\\"')}"/> does not work, probably because replace function does not see actual quote character. 回答1: Parameterize them with <c:set> . <c:set var="search" value='"' /> <c:set

问题 I'm trying to do something in bash with sed that is proving to be extremely difficult. I have a bash script that takes as its first argument a date. The code want to change a line in a text file to include the passed date.

Does anybody know a clever way to get this to work? How can I get a

问题 I need to escape a double quote in inline c# within javascript. Code is below: if ("<%= TempData["Message"]%>" == "") { // code }; Normally, I would just use single quotes like so: if ('<%= TempData["Message"]%>' == "") { // code }; However, TempData["Message"] has single quotes within it (when it contains a link generated by the Html.ActionLink() helper in ASP.NET MVC). So while I could change all the ActionLink helpers inside TempData["Message"] to tags, it's an interesting problem and

问题 Let's say I have a string: something When I escape it in JS I get this: %73%6F%6D%65%74%68%69%6E%67 so I can use this code in JS to decode it: document.write(unescape('%73%6F%6D%65%74%68%69%6E%67')); I need the escape function in PHP which will do the same (will encode something to : %73%6F%6D%65%74%68%69%6E%67 ) How to do that ? 回答1: PHP: rawurlencode("your funky string"); JS: decodeURIComponent('your%20funky%20string'); Don't use escape as it is being deprecated. 回答2: rawurldecode('%73%6F
