What I did
I have created page where am adding datetime picker dynamically but now getting some problem here:
for(i=0;i<5;i++){
counter=i;
var appendTxt = "<div style='display:none' class='divRow5 HideSchedule'><div class='divCellouter4'><div class='divCell2 rowwidth13 brdrStl4'><input name='NEW_STARTdatetime[]' class='dtpkr' type='textbox' readonly='readonly' id='NEW_STARTdatetime["+counter+"]' value='' autocomplete='off' size='10' /></div><div class='divCell2 rowwidth13 brdrSt14'><input name='NEW_ENDdatetime[]' readonly='readonly' autocomplete='off' class='dtpkr' type='textbox' id='NEW_ENDdatetime["+counter+"]' value='' size='10' /></div><div class='divCell2 rowwidth13 brdrSt14'><input name='NEW_START_TIME[]' type='textbox' class='tmpkr' id='NEW_START_TIME["+counter+"]' value='' size='10' /></div><div class='divCell2 rowwidth13 brdrSt14'><input name='NEW_END_TIME[]' type='textbox' class='tmpkr' id='NEW_END_TIME["+counter+"]' value='' size='10' /></div><div class='divCell2 rowwidth8 brdrSt14'><input type='checkbox' name='new_promo_chk[]' id='new_promo_chk["+counter+"]' class='checkbox regular-checkbox big-checkbox' checked /><label for='new_promo_chk["+counter+"]'></label></span> </div></div><div class='divCell2 handcursor'> <img class='del' src='images/delete.png' /></div></div>";
$('[id$="NEW_STARTdatetime\\['+counter+'\\]"]').datetimepicker({
// minDate:'-1970/01/02',
format:'Y/m/d',
onShow:function( ct ){
this.setOptions({
maxDate:$('#NEW_ENDdatetime\\['+counter+'\\]').val()?$('#NEW_ENDdatetime\\['+counter+'\\]').val():false
})
},
timepicker:false
});
$('[id$="NEW_ENDdatetime\\['+counter+'\\]"]').datetimepicker({
//minDate:'-1970/01/02',
format:'Y/m/d',
onShow:function( ct ){
console.log('#NEW_STARTdatetime\\['+counter+'\\]');
console.log($('#NEW_STARTdatetime\\['+counter+'\\]').val());
this.setOptions({
minDate:$('#NEW_STARTdatetime\\['+counter+'\\]').val()?$('#NEW_STARTdatetime\\['+counter+'\\]').val():false
})
},
timepicker:false
});
}
so here now at the time of onshow it takes latest value of counter so my logic get fail,so how to fix that?
This is a simple case of closure surprises. Just move the functionality to a method and call it from the loop passing it counter
in each turn. Like so:
var myMethod = function myMethod (counter){
var appendTxt = "<div style='display:none' class='divRow5 HideSchedule'><div class='divCellouter4'><div class='divCell2 rowwidth13 brdrStl4'><input name='NEW_STARTdatetime[]' class='dtpkr' type='textbox' readonly='readonly' id='NEW_STARTdatetime["+counter+"]' value='' autocomplete='off' size='10' /></div><div class='divCell2 rowwidth13 brdrSt14'><input name='NEW_ENDdatetime[]' readonly='readonly' autocomplete='off' class='dtpkr' type='textbox' id='NEW_ENDdatetime["+counter+"]' value='' size='10' /></div><div class='divCell2 rowwidth13 brdrSt14'><input name='NEW_START_TIME[]' type='textbox' class='tmpkr' id='NEW_START_TIME["+counter+"]' value='' size='10' /></div><div class='divCell2 rowwidth13 brdrSt14'><input name='NEW_END_TIME[]' type='textbox' class='tmpkr' id='NEW_END_TIME["+counter+"]' value='' size='10' /></div><div class='divCell2 rowwidth8 brdrSt14'><input type='checkbox' name='new_promo_chk[]' id='new_promo_chk["+counter+"]' class='checkbox regular-checkbox big-checkbox' checked /><label for='new_promo_chk["+counter+"]'></label></span> </div></div><div class='divCell2 handcursor'> <img class='del' src='images/delete.png' /></div></div>";
$('[id$="NEW_STARTdatetime\\['+counter+'\\]"]').datetimepicker({
// minDate:'-1970/01/02',
format:'Y/m/d',
onShow:function( ct ){
this.setOptions({
maxDate:$('#NEW_ENDdatetime\\['+counter+'\\]').val()?$('#NEW_ENDdatetime\\['+counter+'\\]').val():false
})
},
timepicker:false
});
$('[id$="NEW_ENDdatetime\\['+counter+'\\]"]').datetimepicker({
//minDate:'-1970/01/02',
format:'Y/m/d',
onShow:function( ct ){
console.log('#NEW_STARTdatetime\\['+counter+'\\]');
console.log($('#NEW_STARTdatetime\\['+counter+'\\]').val());
this.setOptions({
minDate:$('#NEW_STARTdatetime\\['+counter+'\\]').val()?$('#NEW_STARTdatetime\\['+counter+'\\]').val():false
})
},
timepicker:false
});
}
for(i=0;i<5;i++){
myMethod(i);
}
Now for the explanation. The onshow will be activated asynchronously, most probably AFTER your loop has finished. Therefore it gets only last value of counter. By moving it into a method, you create a new scope each time you call it. Thus, the passed value is preserved.
PS: I didn't check for any syntax errors.
