上傳.html文件時從html中刪除腳本標記

Question

我給出了一個瀏覽按鈕來上傳文件。我想刪除腳本標記&它的內容，同時uploding .html文件&然後上傳html文件。

如果有人有解決方案，請給我建議。

感謝

Answer 1

你可以只使用.replace或preg_replace的JavaScript和PHP分別。

你的正則表達式模式將<script.*</script>

Answer 2

在客戶端..你可以在HTML追加到iframe

然後，你可以試試..

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

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

然後通過HTML轉移到服務器端。沒有嘗試過，只是一個建議。

Answer 3

1. 上傳文件
2. 讀取文件的文本與fread()
3. 編輯包含該文件的文本變量，從變量<script>刪除 - 使用此：remove script tag from HTML content
4. 寫入新文本與fwrite()
