I've a dijit.form.Combobox field which uses a ItemFileReadStore to pull Its data.
Teh ItemFileReadStore has two attribute per Item value which will be used for form submission , generally Unique Integers and label which is Human Understandable String.
In ComboBox HTML I've done searchAttr="value" labelAttr="label"
When the ComboBox Shows the list it uses teh label Attribute.
But When the User selects one of the Item it shows the value of that Item.
What I want is , The value Attribute will Still be used for Form Submission. But the User will always see the label in the combobox Control.

e.g. I Want to Show The Label for value 3 (Admin) instead of 3
Use FilteringSelect instead of Combobox.
Note: ComboBox only has a single value that matches what is displayed while FilteringSelect incorporates a hidden value that corresponds to the displayed value.
I have tried the following.
var cmbObject = Registry.byId('combo dojo id'); var id =
cmbObject.item.<Code Property>;
You should check if item is null.

I have a dropdown that I have implemented using ReactSelect. It is searchable. But when I search, it queries for any value with the input string. Rather, I need a startswtih filter. If I type A, it should first go to the first filtered value that starts with A.
I tried using a filter on the handler for 'onInputChange' but it is not getting displayed on the dropdown
I have a autocomplete field:
I need to set the default value selected for this dropdown using another control value as shown in:
This control is passed to the form load as shown in:
For example if use cost center is 110 as shown in:
Then the default selected value of the Site lookup dropdown needs to be as shown in:
The tricky part is that your Site-Item field isn't a dropdown but an autocomplete. An autocomplete doesn't know all the possible label/values, but can only find some label/values doing a search by label. So you can't tell an autocomplete "set your value to 110", because it doesn't know what the label corresponding to 110 is.
If you knew the label, you could do this programmatically with an fr-set-label, but here you don't have the label but the value. You can read more about this in the section Setting by value. So, my advice is to use a Dynamic Data Dropdown instead of an Autocomplete field.
So I've added a field with the Dropdown type as Listbox via Screen Painter (SE51).
I've binded the data to the dropdown using the PBO and the VRM_SET_VALUES function.
I have 2 problems with this;
How do you set a selected value to the binded data?
How do you get the value selected by the user.
Data is bound to the dropdown using the following code;
LOOP AT it_zzdelay_text INTO wa_zzdelay_text.
wa_listbox-key = wa_zzdelay_text-zz_delay_reason.
wa_listbox-text = wa_zzdelay_text-zz_delay_reason_text.
APPEND wa_listbox TO it_listbox.
ENDLOOP.
CALL FUNCTION 'VRM_SET_VALUES'
EXPORTING
id = 'ZZ_DELAY_REASON'
values = it_listbox.
The zz_delay_reason is the unique key and the zz_delay_reason_text is the accompanying text.
Update:
According to your code, the field on the screen should be: ZZ_DELAY_REASON
And you also need a global variant with the name.
Then you can Set/Get key value in PBO/PAI:
Set value:
ZZ_DELAY_REASON = 'KEY'.
Get Selected Value(key):
lv_key = ZZ_DELAY_REASON
======================================================
When select list is set by VRM_SET_VALUES, you may notice it is a "Key-Value" pair. The field "KEY" is filled into the screen field value when the user selects drop box.
I could provide detailed information if you attach your code in this question.
Firstly, several prerequisites are to be met to make a functional drop-down:
You item table should have type vrm_values
Values that are showed in the list should be in field text of the item line. Key should be in field key.
PARAMETER should have type LISTBOX.
After all that is done, answers for your questions would be:
Relation of KEY-VALUE is done via vrm_values type. Each line of this type is an drop-down item, where text is a visible text, and key is key.
Parameter automatically gets the key value after user selects the item in the listbox.
Here is the sample code:
REPORT drop-down.
TYPE-POOLS: vrm.
PARAMETERS p_werks LIKE t001w-werks VISIBLE LENGTH 20 AS LISTBOX OBLIGATORY.
DATA: t_werks TYPE vrm_values,
w_line LIKE LINE OF t_werks.
INITIALIZATION.
SELECT werks name1
FROM t001w INTO (w_line-key, w_line-text).
APPEND w_line TO t_werks.
ENDSELECT.
AT SELECTION-SCREEN OUTPUT.
CALL FUNCTION 'VRM_SET_VALUES'
EXPORTING
id = 'P_WERKS'
values = t_werks.
END-OF-SELECTION.
WRITE: / 'Selected factory:', p_werks.
I have a dojo table container embedded within dojo form. I'm able to validate all dijits like textbox, combobox etc and submit the form. But what I need is, submit the form only when a value is changed i.e. if a textbox value is changed, submit the form else don't.
Add a hidden text input field which is empty while loading page. Then After you make a change in your text field check the content in the hidden text field and your respective text field if they are same then don't submit the form.
Dojo input fields maintain the original value in the private attribute of '_resetValue'. Before submitting the form, you can check whether _resetValue is different from .get('value') and submit the data..
If all the attributes are under the Table container, you can fetch the children of the table containers and verify using array.every() function..
var unmodified = array.every(container.getChildren(), function(widget){
return widget._resetValue == widget.get('value');
});
I am using ExtJs 4.1. My page is having a combobox and a button. The comboxbox is having a store which uses a model having 4 fields (UserName,ID (uniqueID),Age,Salary). Name is used as display field and Id is used as value field.
What i want:
When the button is clicked I want to see the selected value in the comboxbox and I want to extract the salary.
Possible solution: Get the id of the selected value from the combobox and find the record in the store and extract the salary for that record.
I was wondering if there is more direct approch or method exposed by ExtJS
on combobox select you can get the salary value like this:
onComboboxSelect: function(combo, records, options) {
var selectedValue=combo.getValue();
var record = combo.findRecord(combo.valueField || combo.displayField, selectedValue);
alert(record.get('salary'));
}
I think this is the important then you can for example save this value and display it when the button is clicked..
