i'm doing calendar full calendar , moment. j's. when click on past day or today, it's supposed return true". if clicked date in future, return false. so, when click on current date (2017-04-06), it's returning true. if click on date after tomorrow (2017-04-08), it's returning false. but, if click on tomorrow date (2017-04-07), it's returning true. there code: ... dayclick: function(date, allday, jsevent, view) { var currentdate = moment(); var clickeddate = date; if(clickeddate.isbefore(currentdate)){ console.log(clickeddate.date()); console.log(currentdate.date()); console.log("true"); } else { console.log(clickeddate.date()); console.log(currentdate.date()); console.log("false"); } }, ...

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

in dom, node , element types have many dynamic properties, e.g., node.textcontent , element.innerhtml , return string representations of nodes’ contents. the dom specifications state these methods “return” domstrings , i.e., string s. they, of course, not specify when , how these strings allocated , computed. text nodes, implementation can return plain-text string content directly. element s must create new strings contain tags , contents of descendant elements. as far can tell, implementation may allocate memory these strings , compute values @ 4 points: immediately, when element first created; lazily, scheduled sometime after element ’s creation; lazily, on demand @ point when getting string property element ; or lazily, on demand whenever string first used (i.e., returned string uses special, externally indistinguishable implementation returned element ’s string properties dynamically generates value when needed). these methods determine when strings’ memory fre...

i use following code convert input comma separated string in inr: decimal input = 1111111111.59m; string result = input.tostring("c", new cultureinfo("en-in")); i want remove trailing 0s now, how do this? for example: decimal input = 1111111111.00m; output should 1111111111 string result = input.tostring("c0", new cultureinfo("en-in")); update: so want output "123.45" input 123.45 , output "123" input 123.00. can't achieve these 2 different formats without conditional operator, string.format() produce 1 output format you. the code simple though: string format = decimal.round(input) == input ? "c0" : "c"; string output = input.tostring(format);
