Hello!
As a professional tool for Java reporting IAD is always better to make users comfortable. To implement the verification of validity, IAD offered two options.
1. Defining the type of input cells. Therefore, it can be done before automatically when the data type refers to the value of the data or e-mail set. With the IAS report, you can easily record the input cell in the tab "General".
2. Preparing to write to a cell. Checking the validity of the expression for the entry and verify the validity manually run the. For example, the entry of verifying the validity of the expression "$ () C5> = 0 & & ($) C5 \\ \\ \\ \\ \\ \\ \\ \\ will u0026lt; = 100" in the cell so that the data value between 1 and 100. You can write the expression to verify the validity of a cell in the form of validation.
Moreever if the input is zero, as will prompt you to enter data? You can JavaScript code in JSP this problem.The JavaScript in the JSP code to be solved as follows:
Control function () (
var keyword = document.getElementById ( 'Repor ...
for (var i = 0, i \\ \\ \\ \\ \\ \\ \\ \\ u0026lt; checkWord.value.length i + +) (
if (checkWord.value.substring (i, i +1) \\ \\ \\ \\ \\ \\ \\ \\ u0026lt, "0
alert ( "Please enter data");
checkWord.value = "";
checkWord.focus ();
return false;
)
)
)
