DeleteHi Vankat
ReplyDeleteI have been using notepad ++ as it is light and quicker than VS but when it came to 53 jquery ajax load it either did not work for textBoxes.focus() Or for $('#' + helpDiv).load('Help.html #' + helpDiv); > I used VS 2013 and it worked fine. My question is is there a way to make it work using notepad ++? Thank you
$(document).ready(function(){
ReplyDelete$('input[type="text"]').on({
'mouseover' : function(){
var DivId = $(this).attr('id') + 'Div';
$('#'+DivId).load('testing1.html #'+DivId);
},
'mouseout' : function(){
var DivId = $(this).attr('id') + 'Div';
$('#'+DivId).html('');
}
});
});
