// This function is suitable for use as an onclick event handler for <a> and// <area> elements. It uses the this keyword to refer to the document element// and may return false to prevent the browser from following the link.function confirmLink() { return confirm("Do you really want to visit " + this.href + "?");}// This function loops through all the hyperlinks in a document and assigns// the confirmLink function to each one as an event handler. Don't call it// before the document is parsed and the links are all defined. It is best// to call it from the onload event handler of a <body> tag.function confirmAllLinks() { for(var i = 0; i < document.links.length; i++) { document.links[i].onclick = confirmLink; }}⌨️ 快捷键说明
