Title: Combobox: setValue within an onSelect
Post by: 2plus2 on September 30, 2019, 07:53:29 PM
I have the following function that is called via a button click. I'm building out a form before displaying the form on a popup. The issue is the onSelect event for the Combobox, which is being triggered by a setValue within the same onSelect - this causes an infinite loop error. I can't use onChange, because onSelect passed the whole row and onChange only passes the new and olde value. I need the row object because I store a bunch of extra data in the returned json object that I use for processing: function confirmNewThresholdDetail() {
clearFormErrors('fmThresholdDetail');
$('#ProcessType').val('New');
$('#InactiveThresholds').combobox({
url: '/ctrls/ajax.aspx?a=getInactiveThresholds&r=' + accountId + '&i=' + $('#ThresholdId').val(),
valueField: 'id',
textField: 'text',
panelHeight: 'auto',
editable: false,
formatter: function (combo) {
if (isNaN(combo.text)) {
return combo.text;
} else {
var gTh = '';
if (combo.GreaterThan == '1') { gTh = '> '; }
return gTh + formatNumber(combo.text, '###,###,###');
}
},
onSelect: function (combo) {
$('#UpperThreshold').prop('disabled', false);
$('#fmThresholdDetail').form('clear');
if (combo.id == "0") {
// new threshold
$('#AccountThresholdDetailId').val("0");
$('#ThresholdDetailId').val('0');
$('#IsStandard_Yes').prop('checked', true);
$('#GreaterThan').prop('checked', false);
$('#NmbrOfApprovers').combobox('setValue', '1');
$('#UpperThreshold').val('');
} else {
if (combo.id != "*") {
// existing inactive
$('#fmThresholdDetail').form('load', combo);
$('#IsStandard_Yes').prop('checked', true);
$('#AccountThresholdDetailId').val(combo.AccountThresholdDetailId);
$('#ThresholdDetailId').val(combo.ThresholdDetailId);
$('#ThresholdRule').text('');
$('#UpperThreshold').val(formatNumber(combo.UpperThreshold, '###,###,###'));
$('#UpperThreshold').prop('disabled', true);
}
}
// reset combo
$('#InactiveThresholds').combobox('setValue', combo.id);
$('#InactiveThresholds').combobox('setText', function () {
if (isNaN(combo.text)) {
return combo.text;
} else {
return formatNumber(combo.text, '###,###,###');
}
});
// Clear any rules
$('#ThresholdRule').text('');
if (combo.id != "*") {
// Show Detail
$('#ThresholdLevelDetail').slideDown();
} else {
$('#ThresholdLevelDetail').slideUp();
}
}
});
$('#ThresholdLevelDetail').hide();
$('#SelectInactiveThresholds').show();
$('#UpperThreshold').prop('disabled', false);
$('#ThresholdCurrency_Txt').text($('#ThresholdCCY_Txt').text());
$('#dlgThresholdDetail').dialog('open').dialog('setTitle', 'New Threshold').dialog('center');
}
I really need a simple solution here because this design pattern is used all over the place. (And yes this is the same 1.3.x to 1.8.x conversion rearing it's ugly head.)

If you want to get the selected row from the 'onChange' event handler, please try this. $('#cb').combobox({
onChange: function(value){
var data = $(this).combobox('getData');
var rows = data.filter(function(r){
return r.value == value;
})
var row = rows[0]
console.log(row)
}
})
