I have a form which has lot of fields consider maybe 100. All of the fields are different such as it could be StartTime DateTime EndTime Value etc.
. User can fill whichever the field they want and keep the remaining fields black.
Now on the Javascript or Node.js
side I need to check if the fields are populated for each of them then based on that I need to create an XML
file. As of now, I am trying to check if each field is populated using the if the condition. If I proceed in this method then I need to write 100 IF
condition to manage all 100 fields which are time-consuming and redundant.
I was just curious if there is any better way of doing it. I tried searching but could not find any relevant post which gives me some sort of idea. If it's duplicate then I am really sorry.
Does anyone have a better idea?
As of now, I am checking something like this:
if(StartTime != '' && StartTime != null && StartTime != undefined)
{
append(StartTime)
}
if(DateTime != '' && DateTime != null && DateTime != undefine)
{
append(DateTime)
}
if(EndTime != '' && EndTime != null && EndTime != undefine)
{
append(EndTime)
}
if(Value != '' && Value != null && Value != undefine)
{
append(Value)
}
.
.
.
.
You could do something like this
const appendIf = () => {
if(val != '' && val != null && val != undefine) {
append(val);
}
};
appendIf(StartTime);
appendIf(DateTime);
appendIf(EndTime);
appendIf(Value);
If all the values are in an array or object, you could also just loop over that:
for(/* whatever for loop is needed*/) {
appendIf(currentValue);
}
