我无法验证表单并停留在同一页面上。下面是我的 javascript 验证,当我收到弹出窗口时它正在工作。
function valueChecks(input){
var reqdFields = false;
var ncFields = false;
var catCheck = false;
var refCheck = false;
var dtCheck = false;
var retval = false;
reqdFields = checkRequiredFields(input) ;
ncFields = checkNonComplianceFields(input);
catCheck = checkCat();
refCheck = checkRef();
dtCheck = subDate();
var mesgNo="0";
if (reqdFields == true){
mesgNo="0";
} else { mesgNo="1";
}
if (catCheck == true){
mesgNo=mesgNo+"0";
} else { mesgNo=mesgNo+"2";
}
if (refCheck == true){
mesgNo=mesgNo+"0";
} else { mesgNo=mesgNo+"3";
}
if (dtCheck == true){
mesgNo=mesgNo+"0";
} else { mesgNo=mesgNo+"4";
}
if (ncFields == true){
mesgNo=mesgNo+"0";
} else {mesgNo=mesgNo+"5";
}
if (mesgNo =="00000"){
retval=true;
}
else if ((mesgNo =="10000")||(mesgNo =="12000")||(mesgNo =="12300")||(mesgNo =="12340")||(mesgNo =="12345")||(mesgNo =="10300")||(mesgNo =="10340")||(mesgNo =="10040")){
retval = false;
alert("Please check that you have filled in all the Mandatory Fields");
}
else if ((mesgNo =="02000")||(mesgNo =="02300")||(mesgNo =="02040")||(mesgNo =="02340")||(mesgNo =="02345")){
retval = false;
}
else if ((mesgNo =="00300")||(mesgNo =="00340")||(mesgNo =="00345")){
retval = false;
alert ("Please enter at least one Reference Value (File Number, STT or BL Number)");
}
else if ((mesgNo =="0004")||(mesgNo =="00045")){
retval = false;
alert ("The Incident Date must be less than or equal today's Date");
}
else if ((mesgNo =="0005")){
retval = false;
alert ("Please enter at least one Non Conforming Party");
}
return retval;
}
这就是我声明我的表格的方式。
<html:form action="/qaeditsrl" onsubmit="return valueChecks(this);" >
<input type=submit value="Submit" name="method" >
有人可以告诉我为什么会出错吗?
