这篇文章主要介绍了js过滤特殊字符输入适合输入、粘贴、拖拽多种情况,需要的朋友可以参考下

 代码如下: function TextValidate(type) {  var code;  var character;  var Lang = document.getElementById('Lang').value;  var err_msg = "";  if (Lang != "Eng") {  err_msg = "文件夹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;  }  }  }
