How to get HTMLB button id using javascript?

[Former Member]

Hello experts,

I am trying to get the generated HTMLB button id by using javascript only and so far what my script could only do is getting the HTMLB input field object. Is there a method that can give me the genereated HTMLB button id that i can use?

Here is my code snippet:

....
            var funcName = htmlb_formid + "_getHtmlbElementId";
            func = window[funcName];
            var inputfield = eval(func("INPUT_FIELD"));
            alert(inputfield.id);
....

In my code above, inputfield.id seems to be not working so the alert message is not shown. I've tried using inputfield.getId() and inputfield.id() but none of those are working. I am trying to find javascript documentations regarding HTMLB to find out all available methods that I could use. Unluckily did not found anything.

Please help me

P.S. Btw, I could not use the IPageContext.getParamIdForComponent(..) because the HTMLB button is not part of the page context. The button is on the parent window of my pop-up.

Hello Carlos,

To get the id of the HTMLB element this is the code/syntax that is used. These two lines of code are

standard and will have to be there in the JavaScript Function:

var funcName = htmlb_formid+"_getHtmlbElementId";
func = window[funcName];
var <b>HTMLBElementId</b> = eval(func("<b>idOfHTMLBElement</b>"));

For the UI elements to be capable of client side eventing, the jsObjectNeeded attribute of the UI element

must be set to true, e.g.

<hbj:button
    id="Button"
    text="Submit"
    width="100px"
    tooltip="Click to Submit"
    onClientClick="Test()"
    disabled="false"
    <b>jsObjectNeeded="true"</b>/>

You will find the JavaScript API for some of the UI elements at the following <a href="http://help.sap.com/saphelp_nw04/helpdata/en/43/067941a51a1a09e10000000a155106/frameset.htm">link</a>:

Hello Bala,

I have tried using your code but still got the problem. I alerted the variable HTMLBElementId and got "[object Object]". Instead of the generated id of HTMLB.

Thanks,

Hello Carlos,

Just curious., as to why you need the UI element ID?, because most of the validations could be done without knowing the explicit ID of a UI element.

I guess you've already reffered the link I've mentioned in my previous reply. However, refer this one for a detailed account on validation part. This document gives a BIG picture on client side validation.

Hello Bala,

Ok, first of all I'm sorry if I didn't inform you the reason behind why I need the explicit ID of a HTMLB button and thank you for giving me the link

Actually the thing that I really want to know is the Object ID of the HTMLB button, because I need to pass that value to "function htmlbSubmit(elem,eventType,formID,<u>objectID</u>,eventName,paramCount,param1,param2,param3,param4,param5,param6,param7,param8,param9)". After some investigations that I made, I realized that the Object ID is part of the HTMLB button generated ID (saw it by viewing the page source). So, if I have the explicit ID then I can get the Object ID from it.

Thanks for the help.

Regards,

Carlos
