onsearch事件对于搜索非常有用,即用户在输入元素中按ENTER或“ x”键。<input>的类型是search,因为它是供用户搜索的。Internet Explorer,Firefox和Opera不支持onsearch事件。
您可以尝试运行以下代码,以了解如何在JavaScript中实现onsearch事件。
<!DOCTYPE html> <html> <body> <p>Write what you want to search below and press "ENTER".</p> <input type = "search" id = "newInput" onsearch = "searchFunc()"> <script> function searchFunc() { var a = document.getElementById("newInput"); document.write("Searched = " + a.value); } </script> </body> </html>
