Javascript in process input variable

[sagar....@flowian.com]

Hi Team,

In my web interface I have taken one array widget. In which one column "Total" is of type Number.

I am trying to set values in this array widget's "Total" column from Javascript which is included in the "Input Variable" tab as shown below

<@script env="javascript">

my_array.total[0]=12;

</@script>

But the error I got is like this ------>

Invalid javascript.: TypeError: Cannot set property "0.0" of undefined to "12" (<
function ...>#129)

"my_array" is the name of array widget.

Regards,
Sagar

Hi Sagar,

Are you able to get the Column "total" in your process initial parameters? If not,you can check the check box "initialize" in the column "Total" of the array widget and no need to put any default value.This will prevent error in execution in case you leave the particular column(total)  empty and trigger the process.

To set value, you can use the following code: <@script env="javascript">

                                                                   setVariable("my_array.total[0]",12)

                                                                   </@script>

Thanks & Regards

Hi Bidisha,

When I use the below code for setting the array value

<@script env="javascript"> setVariable("my_array.total[0]",12); </@script>

It will add new node to the "my_array". I want that the value should add into my_array.total[]. Rather than it creates "my_array.total[0]" new node.

Sagar

Hi Sagar,

In above script, for sure we are not adding any new row(node) for the array widget, it only sets the value of existing array column based on row index of array.

Please send complete code and process configuration and related run-time screenshots to analyze and suggest you further.

Regards,

Murali

Hi Sagar,

As per your first post you are getting error while assigning the value in array. This is because of you are using array index to assign value but internally it will not found any array column.

Have you initialized the array column "Total" ?

To do so please follow below steps:

1. Initialize the array column. Please find the screenshot for more information.

2. Use your code in process activity (input variable).

Let us know if you are still getting the same problem.

Thanks & Regards,

Hi Sagar,

For that, you need to make a small change in the freemarker code I provided you above: 

<@script env="javascript">

setVariable("my_array.total[0]",["12"]) [ pass the value 12 in array format]

[Bidisha Das]

Hi Sagar,

Just missed one thing. No need to use index[0]. Please follow the code below:

<@script env="javascript">

setVariable("my_array.total",["12"]) [ pass the value 12 in array format]

[sagar....@flowian.com]

Hi Bidisha and Shobhit,

Thanks for your support.

I have implemented shobhit's solution and its working fine.

Sagar
