Is there a problem adding properties (or methods) directly to DOM Element Objects? Potentially. There is no web standard that says you can add arbitrary properties to DOM nodes. They are ‘host objects’ with browser-specific implementations, not ‘native JavaScript objects’ which according to ECMA-262 you can do what you like with. Other host objects will … Read more
There are a few steps you need to take to properly store this information in your localStorage. Before we get down to the code however, please note that localStorage (at the current time) cannot hold any data type except for strings. You will need to serialize the array for storage and then parse it back … Read more
Check the jQuery FAQ… You can use the length property of the jQuery collection returned by your selector: if ( $(‘#myDiv’).length ){}
As lyyons pointed out in the comments, more idiomatic and lodashy way to do this would be to use _.remove, like this _.remove(obj.subTopics, { subTopicId: stToDelete }); Apart from that, you can pass a predicate function whose result will be used to determine if the current element has to be removed or not. _.remove(obj.subTopics, function(currentObject) … Read more
There’s one string in the intern pool, which will be reused every time you run the code. Then there’s the extra string which is constructed each time you run that line. So for example: for (int i = 0; i < 10; i++) { String s = new String(“abcd”); } will end up with 11 … Read more
function updateObject(object, newValue, path){ var stack = path.split(‘>’); while(stack.length>1){ object = object[stack.shift()]; } object[stack.shift()] = newValue; }
You can use the new OBJECT library feature introduced in CMake 2.8.8. The idea is explained here. Basically, the OBJECT library is a similar concept to the convenience library known from Autotools to group object files. Check the complete CMake OBJECT library tutorial.
The question states that he wants to find the object with the greatest id, not just the greatest id… var myArray = [{‘id’:’73’,’foo’:’bar’},{‘id’:’45’,’foo’:’bar’}]; var max = myArray.reduce(function(prev, current) { if (+current.id > +prev.id) { return current; } else { return prev; } }); // max == {‘id’:’73’,’foo’:’bar’}
I think that the section 15.6. The select clause covers what you’re trying to achieve: 15.6. The select clause … Queries can return multiple objects and/or properties as an array of type Object[]: select mother, offspr, mate.name from DomesticCat as mother inner join mother.mate as mate left outer join mother.kittens as offspr Or as a … Read more
Using Java-8 Collection#removeIf myList.removeIf(obj -> obj.id == 10); With Java-7 you’ll have to use iterator: for(Iterator<MyType> iterator = myList.iterator(); iterator.hasNext(); ) { if(iterator.next().id == 10) iterator.remove(); } Note that list iteration is necessary in any case. In Java-8 removeIf method it’s just performed internally.
