這篇文章主要介紹了js過濾特殊字符輸入適合輸入、粘貼、拖拽多種情況,需要的朋友可以參考下
代碼如下: function TextValidate(type) { var code; var character; var Lang = document.getElementById('Lang').value; var err_msg = ""; if (Lang != "Eng") { err_msg = "文件夾名稱不能包含下列字符之一:n / : * ? " < > | & , "; } else { err_msg = "A Folder Name cannot contain any of the following characters:n / : * ? " < > | & ,"; } if (type == "input") { code = window.event.keyCode; } else if (type == "paste") { code = window.clipboardData.getData('Text'); } else if (type == "Drop") { code = window.event.dataTransfer.getData('Text'); } else { code = arguments.callee.caller.arguments[0].which; } var character = String.fromCharCode(code); var txt = new RegExp("[*,&,,/,?,|,:,<,>,"]"); if (type == "input") { if (txt.test(character)) { alert(err_msg); if (document.all) { window.event.returnValue = false; } else { arguments.callee.caller.arguments[0].preventDefault(); } } } if (type == "paste" || type == "Drop") { if (txt.test(code)) { alert(err_msg); window.event.returnValue = false; } } }
