I have created an app with date range fields.
Here is the javascript used to get current date. ( works fine )
function setCurrDate()
{
var d = new Date();
var currMonth = d.getMonth() + 1;
var currDate = d.getDate();
var currYear = d.getFullYear();
time =
(currMonth < 10 ? "0" : "") + currMonth + "/" +
(currDate < 10 ? "0" : "") + currDate + "/" +
currYear + " " ;
theInput = document.getElementById("EndDate");
theInput.value = time;
}
This is part of the form...
<form>
<INPUT TYPE="text" NAME="EndDate" Size="8" Value="<%=EndDate%>">
</form>
What I need to do is store any updates to the EndDate by the user (if any).
Right now all it's doing is being overwritten during the load or submit of the page because I'm using the <body onload="setCurrDate()"> and it overwrites the EndDate field data.
Any suggestions?
Thanks in advance.

Hi swebster, welcome to TSDN!
Do you mean you want to update EndDate in a database?
Hi swebster, welcome to TSDN!
Do you mean you want to update EndDate in a database?
No, I use the EndDate as part of a query string to submit a search query.
So basically, on form load I need the field to equal the current date and if the user updates the date to be something earlier I need to dynamically store the new date in the EndDate variable.
clear as mud? :-)
So how are you going to use this EndDate variable? If it's part of a form, it will get passed to the next page on submit.
Yes, but I can't have the users date over written in EndDate field after the initial results are rendered. Also, I am encoding the string in the URL and the users update to the date field is being captured in the result string but when the form refreshes the current date is placed back in the EndDate field.
I know I am passing the EndDate parameter correctly, so it's just that I need a way to if/else it rather than using the onload option.
I am getting closer... just getting snagged on the syntax.
String EndDate = request.getParameter("EndDate");
if(EndDate == null)
{
EndDate = "" need to set the current date here "" ;
}
This way I would be able to use else and manage the users entry.
It's really more like;
String EndDate = request.getParameter("EndDate");
if(EndDate == null)
{
EndDate = setCurrDate(); // execute js function if EndDate field is null.
}
In that case, set the value with the server code as you already have done and in your onload function, check if EndDate has already been set by checking the input text field.
Yes that is the direction I am leaning towards but none of my syntax is working.
I just tried adding an if statement in the <body tag but that doesn't work.
<body if (EndDate == null) { onload="setCurrDate()" } >
---- or ----
set it in the jsp like this..
String EndDate = request.getParamter("EndDate");
if (EndDate == null )
{ EndDate = setCurrentDate() };
But neither work.
Thanks for all your replies aCoder!
I have successfully added an if statement to the function and it's working now with the onload.
function setCurrDate()
{
if ( queryForm.EndDate.value == '' ) {
var d = new Date();
var currMonth = d.getMonth() + 1;
var currDate = d.getDate();
var currYear = d.getFullYear();
time =
(currMonth < 10 ? "0" : "") + currMonth + "/" +
(currDate < 10 ? "0" : "") + currDate + "/" +
currYear + "" ;
theInput = document.getElementById("EndDate");
theInput.value = time;
}
}
<body onload="setCurrDate()">

No problem, glad you got it working.
