Thanks for the input. I'll have a look at jQuery then!

Regards,

Robin

Hi

it is already inside dhis2 (for every dhis2 page). no need for external import

Hi,
Thanx. Is jquery available inside data entry form on the fly or has to link it separately to outside library.

Hi,
Thanks a lot. In fact I'm a medical doctor and have limited knowledhe in Javascript. I managed to get it done with following javascript I created.

height enterd in cm and weight in kg.

<script type="text/javascript">

function updateBMI() {
var ht = document.getElementById("HeightID-val").value;
var wt = document.getElementById("WeightID-val").value;
if(ht!="" && wt!=""){
var bmi = wt/(ht*ht/10000);
bmi = +bmi.toFixed(2);
}else{
var bmi ="Enter Height and Weight";
}
var inputbmi= document.getElementById("BMI-ID-val");
inputbmi.value = bmi;
}
updateBMI();

</script>
It serves the purpose it seems. Pls suggest any modifications

yes you can use custom data entry form and add some js script like onchange event on weight and height.

the event handler should then calculate the bmi and update the text field bmi.

do you have any technical person to do this? if not give me your account i can help

I'd like to add something to this.
For example, if we have a data entry form (BMI) for a program stage if we have height and weight input boxes/data elements is there a way to calculate BMI?
is it only possible by using javascript/webapp

Hi

I believe the calculated data value (now as indicator) can only be seen after an aggregation is run.
In addition, in some forms in some countries like VN, auto-calculated data elements some time can be input by users.

In VN, we use Javascript to achieve this. However, it is quite complicated. Imagine that you have to rebuild a spreadsheet engine.

Important lesson learnt was if a dataelement is auto-calculated, make sure no one can change it manually. Otherwise, you end up with very low data quality.

Hi Robin,

You can simply use an indicator to do this.

In case you have not seen it, we have extensive documentation on the use of indicators here

https://www.dhis2.org/doc/snapshot/en/user/html/ch13.html#indicator_maintenance

It should also be possible to calculate the value from other data, not contained in the data entry form, IF it exists for the same orgunit and period.

Best regards,
Jason

Dear all,

Does anyone know if there's a way to have auto-calculated fields in data entry forms? This auto-calculated field would then be available for further reporting and indicator calculation (i.e. it is a data element calculated based on other data elements in the same entry form).

Actually, if it would be possible to calculate data elements based on other data elements outside of a data form, that would be great too (but if I remember well this is currently not possible).

Thanks for any ideas,

Robin
