how to parse the html input variable into jelly evaluate

shekar038 · ‎08-22-2016

I pasted piece of HTML UI page script below. My requirement to dyanmically change the Due date(project_due_date) according to months selected . The due date should to be equal to current + months(selection). I am trying to perform this basic calculation using g:evaluate and assign the result jvar_ variable to date field.

But I am having difficulty in parsing the number months (due_months) selected into the jelly evaluate.

Also if you can help in changing date field as display only woudld be great full .i have tried many option like disabled="disabled" .Noting seems to work.Jelly is wierd and crazy to work with.

any help is highly appreciated.

<td>

Due date

</td>

<td>

<option value="0">Select</option>

<option value="3">3 months</option>

<option value="6">6 months</option>

</select>

<g:evaluate var ="jvar_due_date" objects="true" jelly ="true">

var today = new GlideDateTime();

today =gs.nowDateTime();

today.addMonths(${due_months});

</g:evaluate>

<g:ui_date id="project_due_date" name="project_due_date" value="$[jvar_due_date]" />

</td>

</tr>

Hi Hemashekar,

You will almost certainly want to make sure the due_months variable has been cast as an integer. Out of curiosity, where is your due_months coming from / being set as a variable?

I'm guessing you also want to pass back the "today" value to jvar_due_date - don't forget to pass it back out at the end of the evaluate:

<g:evaluate var ="jvar_due_date" objects="true" jelly ="true">

var today = new GlideDateTime();

today =gs.nowDateTime();

today.addMonths(parseInt(${due_months}));

today

</g:evaluate>

Let me know how you get on!

Hi Alex,

Thanks for your reply.

due_months will be passed from the drop down selection option just above the evaluate in the html.

<option value="0">Select</option>

<option value="3">3 months</option>

<option value="6">6 months</option>

</select>

parseInt() does here?

thanks

Hi Hemashekar,

parseInt() forces javascript to interpret the value you are pulling from the drop down as a number - right now he thinks it's a string. The addMonths function is expecting a numeric value, not a string. Link to API reference

Thanks Alex for your response. Do you think the will dynamically change the value of the project_start_date every time I select the month option.

Or writing javascript just for this operation is good way??
