JS代码防止SQL注入的方法(超简单)

//过滤URL非法SQL字符var sUrl=location.search.toLowerCase();var sQuery=sUrl.substring(sUrl.indexOf("=")+1);re=/select|update|delete|truncate|join|union|exec|insert|drop|count|'|"|;|>|<|%/i;if(re.test(sQuery)){alert("请勿输入非法字符");location.href=sUrl.replace(sQuery,"");}

function AntiSqlValid(oField ){re= /select|update|delete|exec|count|'|"|=|;|>|<|%/i;if ( re.test(oField.value) ){//alert("请您不要在参数中输入特殊字符和SQL关键字！"); //注意中文乱码oField.value = ";oField.className="errInfo";oField.focus();return false;}

txtName.Attributes.Add("onblur", "AntiSqlValid(this)");//防止Sql脚本注入
