上载.html文件时，从html中删除脚本标签

Question

I have given a browse button to upload a file. I want to remove script tag & it's content while uploding .html file & then upload html file.

If anybody have solution please suggest me.

Thanks

Answer 1

You can just use .replace or preg_replace for Javascript and PHP respectively.

Your regex pattern would be <script.*</script>

Answer 2

On the client side.. you can append the html to an iframe

Then, try something like..

$(..documentElement).find('script').remove();

var htmlContent = $(..documentElement).html();

Then pass the html over to server-side. Haven't tried it, just a suggestion.

Answer 3

1. Upload the file
2. Read the text of the file with fread()
3. Edit the variable that contains the text of the file, delete from variable the <script> - use this: remove script tag from HTML content
4. Write the new text to the file with fwrite()
