Question

代码有点长，不让发，只截取了部分，是ChinaNet登录页面的源代码，不知道各地的一不一样，附网址：

其中“手机帐号登录”选项下的“登录”按钮，OnClick后执行的是defaultOnCheck(2)，我js只学了大概，感觉像是调用了一个函数defaultOnCheck(2)，但是到处找都找不到，开头的那几个js文件main_vf.js, getpw_vf.js, certify.js, usertype.js全都找过了，没有这个函数，请问这是一个函数吗，按“登录”按钮后执行了什么呢？俺水平低，大家就不要打击我了，这个“登录“是怎么搞的？十分感谢！

Answer 1

在main_vf.js 185行function defaultOnCheck(loginType){        if(loginType)            defaultIndex=loginType;                if(document.getElementById("UserName"+defaultIndex).value==""){            alert("请输入账号");return ;        }        if(document.getElementById("PassWord"+defaultIndex).value==""){            alert("请输入密码");return ;        }        //if(document.getElementById("verifycode"+defaultIndex).value==""){        //  alert("请输入验证码");return ;        //}                document.getElementById("UserName").value=document.getElementById("UserName"+defaultIndex).value;        document.getElementById("PassWord").value=document.getElementById("PassWord"+defaultIndex).value;        //document.getElementById("verifycode").value=document.getElementById("verifycode"+defaultIndex).value;        document.getElementById("UserType").value=defaultIndex;        var username = document.getElementById("UserName").value;        username=trim(username);        document.getElementById("UserName").value=username;        if(defaultIndex==1){            if(allCertify(1)==false){return;}            if(realmName!=""){                document.getElementById("province").value="";            }else{                var province=document.getElementById("prov").value;                var srname="normal";                                if(/^.*CHCARD.*$/.test(sectionName)==true){                    document.getElementById("isChCardUser").value="true";                    username=username.substr(0,2).toUpperCase()+username.substr(2);                    document.getElementById("UserName").value=username;                }                                if(/^.*WCARD.*$/.test(sectionName)==true){                    document.getElementById("isWCardUser").value="true";                    username=username.substr(0,1).toUpperCase()+username.substr(1);                    document.getElementById("UserName").value=username;                }                                               if(isCDMAFlag||/^.*CDMA.*$/.test(sectionName)==true){                    srname="CDMA";                }                for(i=0;i<provs.length;i++){                    if(provs[i]!=null&&provs[i].name==province){                        for(j=0;j<provs[i].realm.rule.length;j++){                            if(provs[i].realm.rule[j].name==srname){                                document.getElementById("province").value=provs[i].realm.rule[j].exp;                                }                        }                    }                }            }        }else if(defaultIndex==2){            sectionNO=-1;            sectionName="";            sectionNO=section(username);            if(sectionNO==-1||/^.*CDMA.*$/.test(sectionName)!=true){                //非天翼手机号码 判断是否是异网手机                if(otherUserTypeCertify("")==false){                    alert("请输入手机号码！");                    return;                }                document.getElementById("UserType").value=defaultIndex+1;            }else{                var srname="CDMA";                for(j=0;j<provs[sectionNO].realm.rule.length;j++){                    if(provs[sectionNO].realm.rule[j].name==srname){                        document.getElementById("province").value=provs[sectionNO].realm.rule[j].exp;                    }                }            }                    }        //alert("usertype="+document.getElementById("UserType").value+"|province="+document.getElementById("province").value+"|username="+document.getElementById("UserName").value);        document.forms[0].action = "/authServlet";        document.forms[0].submit();            }

Answer 2

VS中CTRL-F 查找整个解决方案：defaultOnCheck

Answer 3

直接执行代码alert(defaultOnCheck);马上就看到函数代码了

Answer 4

楼上的解决方法不错 楼主以后可以使用 谷歌浏览器 和firefox等 进行调试 这样就好找了 不用这么困难了

Answer 5

十分感谢各位的回答，不过不知道为什么，chrome的搜索总是出错，明明有但总显示找不到
