Hi All,
I am a newbie with regard to ServiceNow (but not the first time doing software development ;o)
I am using the weekend to get my feet wet with client scripting for the new demand management application of my company. We have a brandnew instance, provided by ServiceNow a couple of weeks ago. So most of the scripts already work very well.
Where I have got stuck after hours of googeling and searching the community is the following: I would like to implement a client script, that updates in the table
[DEMAND] an integer field with an amount, translating the famous ServiceNow-T-Shirt-Size (string) into Euros, e.g.
if size = "small", the amount is < 100K Euro
if size = "medium", the amount is < 500K Euro ...
The trigger for the "onchange" client script is the field 'size' (out-of-the-box in the table [DEMAND], a string with 5 options, I have entered a 6th option (Extra-Small)).
The field to be updated is 'u_t_shirt_size_numeric', in the very same table [DEMAND].
My problem is, that I can edit in the form the T-Shirt-Size in any form, but the script just does not get called. Can this be linked to the fact that 'size' is a choice field. My scripts get called in all other field types I have tried so far.
And yes, I have checked 5 times, that the name of the field in the table is correctly selected in the script.
Thx a lot, Andreas
=====================================================================
And this is the code, but as I said, never called (thus possibly not correct scripted):
=====================================================================
function onChange(control, oldValue, newValue, isLoading, isTemplate) {
// Bugfixing: display of parameters of the function. However, these alerts never show up, thus the function is not called when editing the field "size"
alert('control: ' + control);
alert('old value: ' + oldValue);
alert('new value: ' + newValue);
alert('isLoading: ' + isLoading);
alert('isTemplate: ' + isTemplate);
// The usual "entry-check" for "newValue == ''" should not be relevant here, as there is no "undefined" or "empty" T-Shirt-Size in the choice list
if (isLoading) {
return;
}
var editedTShirtSize = newValue;
var validTShirtSize = false;
// This case of empty T-Shirt-Size should not exist if the field has been edited, as there is no "undefined" or "empty" T-Shirt-Size in the choice list
if (editedTShirtSize == '') {
g_form.setValue('u_t_shirt_size_numeric', '0');
validTShirtSize = true;
}
if (editedTShirtSize == 'xsmall') {
g_form.setValue('u_t_shirt_size_numeric', '50');
validTShirtSize = true;
}
if (editedTShirtSize == 'small') {
g_form.setValue('u_t_shirt_size_numeric', '100');
validTShirtSize = true;
}
if (editedTShirtSize == 'medium') {
g_form.setValue('u_t_shirt_size_numeric', '500');
validTShirtSize = true;
}
if (editedTShirtSize == 'large') {
g_form.setValue('u_t_shirt_size_numeric', '1000');
validTShirtSize = true;
}
if (editedTShirtSize == 'xlarge') {
g_form.setValue('u_t_shirt_size_numeric', '1500');
validTShirtSize = true;
}
if (editedTShirtSize == 'xxlarge') {
g_form.setValue('u_t_shirt_size_numeric', '2500');
validTShirtSize = true;
}
// Safety measure: if another choice gets added to the T-Shirt-Size, an error message should occur, as no numeric value has been defined
if (validTShirtSize == false) {
alert('For your selected T-Shirt-Size so far no numeric values has been defined. The field "T-Shirt-Size numeric (Euro)" was not updated. Please contact Technology area');
//would be good to also trigger an email to all admins / members of Technology Group
}
}
