You can create the folder's tar file by 7z command . Then fire the browse folder dialog. Now, you can get the folder's tar file name from the input element. <html> <head> <title>show a browse folder dialog to select all files in a specified directory recursively in JavaScript</title> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script> </head> <body style="background:lightgray"> <p>Click the button to test:</p> <input type="file" id="fileUpload" directory webkitdirectory multiple> </br> <textarea id="edit" style="height:200px;width:240px"> Click the select file button to select files, then show the select file names. </textarea> <script> $...

parse a html string in javascript

-

So you have to convert these characters back to <,> character. You have to convert the html string to a single line. If the html string has multiple lines with a \n character. <html> <head> <title>parse a html string in javascript</title> </head> <body> <p>Click the button to test:</p> <button onclick="myFunction()">Result</button> </br> <textarea style="width: 400px;height: 200px;"id="demo"><html><head><title>titleTest</title></head><body><a href='test0'>test01</a>...
