How to Access Web Item Values in Web Application Designer

[Former Member]

Hi Guru's

I want to access value caontained in a particular webitem dynamically in my custom script .for example

I have a DROPDOWN web item that is attached to a variable ( CALYEAR)

When I select a particular calyear, I need to capture that value in a Javascript variable .

This would enable me to filter other providers that doesn;t use the same variable using the set filter function .

Please send across code snippets / of function library in case any body has them

I am using WAD 7.1.

Thanks for your help

Regards

Hi Nikhil,

You can achieve that by creating a script item and writing the javascript in that code: I'am here showing u to do that for the text_item.

In the XHTML layout where your TEXT_ITEM tag is present please add the tag like:

<bi:TEXT_ITEM name="TEXT_ITEM_1" designheight="70" designwidth="200" >

<bi:TEXT_BINDING type="CHOICE" value="CHARACTERISTIC_TEXT_BINDING" >

<bi:CHARACTERISTIC_TEXT_BINDING type="COMPOSITE" >

<bi:DATA_PROVIDER_REF value="DP_2" />

</bi:CHARACTERISTIC_TEXT_BINDING>

</bi:TEXT_BINDING>

</bi:TEXT_ITEM>

in the Script web item write the code like:

function show_data()

{

var x = document.getElementById("data") ;

var str = x.innerText;

var arr = new Array();

arr = arr.split("\n")

//Now all the data will be available in the array arr, use it like as u use an array in

C

for (i=0;i<arr.length;i++)

{

document.write( arr ); //taking the value

}

}

call your function on desired action.

Please write if not clear.

Refer to below thread, (same issue as of urs)

Hello Deepika ,

Thanks for the response my dropdown item look like the following

<bi:DROPDOWN_ITEM name="DROPDOWN_ITEM_1" designheight="32" designwidth="122" >

<bi:WIDTH value="122" />

<bi:HEIGHT value="32" />

<bi:DATA_BINDING_TYPE type="CHOICE" value="CHARACTERISTIC_SELECTION" >

<bi:CHARACTERISTIC_SELECTION type="COMPOSITE" >

<bi:DATA_PROVIDER_REF value="DP_1" />

<bi:CHARACTERISTIC value="0MAT_PLANT__BUSLINE" text="Business Line" />

<bi:LINKED_DATA_PROVIDER_REF_LIST type="ORDEREDLIST" >

<bi:LINKED_DATA_PROVIDER_REF index="1" value="DP_3" />

</bi:LINKED_DATA_PROVIDER_REF_LIST>

</bi:CHARACTERISTIC_SELECTION>

</bi:DATA_BINDING_TYPE>

</bi:DROPDOWN_ITEM>

In your function

function show_data()

{

var x = document.getElementById("data") ;

var str = x.innerText;

var arr = new Array();

arr = arr.split("\n")

.....

there is no element by name "data"

should I use the name reference for the same like "DROPDOWN_ITEM_1"

Where is the ID given to a dropdown web item

Can you please elaborate ont he same

Hi Nikhil,

1. there is no element by name "data".

Please add 'span' tag here -

---

Its a html tag, '<' span id = "data" '>'

<bi:DROPDOWN_ITEM name="DROPDOWN_ITEM_1" designheight="32" designwidth="122" >

<bi:WIDTH value="122" />

<bi:HEIGHT value="32" />

<bi:DATA_BINDING_TYPE type="CHOICE" value="CHARACTERISTIC_SELECTION" >

<bi:CHARACTERISTIC_SELECTION type="COMPOSITE" >

<bi:DATA_PROVIDER_REF value="DP_1" />

<bi:CHARACTERISTIC value="0MAT_PLANT__BUSLINE" text="Business Line" />

<bi:LINKED_DATA_PROVIDER_REF_LIST type="ORDEREDLIST" >

<bi:LINKED_DATA_PROVIDER_REF index="1" value="DP_3" />

</bi:LINKED_DATA_PROVIDER_REF_LIST>

</bi:CHARACTERISTIC_SELECTION>

</bi:DATA_BINDING_TYPE>

</bi:DROPDOWN_ITEM>

Close the span tag here:

'<' / Span '>'

please remove ' ' when u place the code, i have to do that as other wise the messanger wil read it as a html tag and remove it.

Now use the code as it is.

2.should I use the name reference for the same like "DROPDOWN_ITEM_1"

No.

3. Where is the ID given to a dropdown web item - I provided that now.

I tried this code with text_item. (other's also used the same ajay & recardo, worked succesfully in our case) . If u have any problem further then let me know.

Thanks.

Nikhil please look out for the span tag syntax on net, and in its id please set data as id = "data",

Thread removes the span tag,

Analyse the Generated HTML and the you'll be able to fing the dropdown box item

Hello,

where do I place the span-tag if I want to read a InfoField?

Currently my code is as followed:

<bi:INFO_FIELD_ITEM name="INFO2" designheight="300" designwidth="300" >

<bi:DATA_PROVIDER_REF value="DP_1" />

<bi:INFORMATION_ELEMENT_LIST type="ORDEREDLIST" >

<bi:INFORMATION_TYPE type="CHOICE" index="1" value="CHARACTERISTIC_LIST" >

<bi:CHARACTERISTIC_LIST type="ORDEREDLIST" >

<bi:CHARACTERISTIC index="1" value="/RB05/RBHMATNR" text="/RB05/RBHMATNR" />

</bi:CHARACTERISTIC_LIST>

</bi:INFORMATION_TYPE>

</bi:INFORMATION_ELEMENT_LIST>

</bi:INFO_FIELD_ITEM>

Any hints and tips are welcome!
