Validating field in FormAPI

In my DCT, I have a text field, say fieldABC.

To make all letters in the field upper case, I add an ItemHander as follows:

IWEventRegistry.addItemHandler("/rootcontaineritem/fieldABC", "onItemChange", toUpperCase);

whose associated function works as follows:

function toUpperCase(item) {
item.setValue(item.getValue().toUpperCase());
}

Similarly, I could add an ItemHandler to left trim spaces from the text, as follows:

IWEventRegistry.addItemHandler("/rootcontaineritem/fieldABC", "onItemChange", leftTrim);

whose associated function works as follows:

function leftTrim(item) {
var objRegExp = /^(\s*)(\b[\w\W]*)$/;
item.setValue(item.getValue().replace(objRegExp, '$2'));
}

How do I combine the two functions on one field in the DCT? I would like to be able to fill an array with true or false entries which are associated with given function calls. In the above example, it would be desirable to populate an array with true and false value each associated with a given function. Say something like

var itemArray = new Array(2)
itemArray[0] = true; // toUpperCase
itemArray[1] = false; // leftTrim

and then pass in this array as a parameter in the addItemHandler, and then only call the functions which are true. This way, I am hopefully able to apply many functions against a single field.

Any ideas? Help is much appreciated.

Hi,

Can u more elaborate ur problem.

IWEventRegistry.addItemHandler("/rootcontaineritem/fieldABC", "onItemChange", toUpperCase);

function toUpperCase(item) {
item.setValue(item.getValue().toUpperCase());
}

IWEventRegistry.addItemHandler("/rootcontaineritem/fieldABC", "onItemChange", leftTrim);

whose associated function works as follows:

function leftTrim(item) {
var objRegExp = /^(\s*)(\b[\w\W]*)$/;
item.setValue(item.getValue().replace(objRegExp, '$2'));
}

How do I combine the two functions on one field in the DCT?

I hope this will work.
IWEventRegistry.addItemHandler("/rootcontaineritem/fieldABC", "onItemChange", toUpperCase);

whose associated function works as follows:

function toUpperCase(item) {

item.setValue(item.getValue().toUpperCase());
item.setValue(item.getValue().replace(objRegExp, '$2'));

}
Another way of doing this , you can take a intermidiate temprory variable.

Thx, Nidhi,

I did implement a similar script to the one you posted, and it works fine. Only drawback, is that I want to reuse the functions for different fields, and as such don't want to tie the functions together. I am hoping for the ability to call either or both (or more later) depending on the situation.

Thx for the help.

Christian,

JonathonG and I will be covering this topic in our presentation at GearUp this year. Unfortunately, we will not be making the solution available until after GearUp. I will try to remember to come back to this post and add a link to the tech library article when it is created.

Can you not have a 3rd function that you call from the event handler and simply calls the toUpperCase and leftTrim functions?

If you need the choice of one/other/both in the future based on some DCR value you can add the conditional code the the wrapper function.

Here's a link the the tech article that you can use to accomplish this:
