How Do I Get Records Length From A QueryTask?

ChrisSergent

I have entered in the parameters for a query here: Query: Sign (ID: 0)

I return a total of 8 signs in this query, but I want to connect the returned information to a form using previous and next buttons to increment or decrement by one for each button click to assign that specific record to the form and then switch forms once the max or minimum number has been reached.

Just to be safe, my parameters were as follows:

Where: SUPPORTID='691'

Out Fields: *

Order By Fields: OBJECTID

Everything else was the default.

Chris,

   So when you run the initial query you get an array of features. So just use that array of features and use your position in the array (your index)  to return the individual record from your array when the user clicks next just add to your index var.

var myArr = queryResuts.features;

var myRecLen = myArr.length - 1;

var myIndex = 0;

var frmRec = myArr[myIndex];

//next button clicked

myIndex++;

if(myIndex <= myRecLen){

     frmRec = myArr[myIndex];

}else{

     myIndex = myRecLen;

     frmRec = myArr[myRecLen];

}

//previous button clicked

myIndex--;

if(myIndex >= 0){

     frmRec = myArr[myIndex];

}else{

     myIndex = 0;

     frmRec = myArr[0];

}
