What's the point of the javascript navigator.javaEnabled function?

由 霸气de小男生 提交于 2019-12-24 18:46:31
问题 The navigator object has a javaEnabled function that indicates if the browser has javascript support. This seems to be a little odd: If JS is indeed enabled the function will return true, well obviously. If JS is disabled it will return < nothing > since it is never run, javaScript is disabled. I must be missing something here, or is it really that useless this function? 回答1: java != javaScript navigator.javaEnabled checks for the presence of Java , not JavaScript. Reference This must be a

由 天涯浪子 提交于 2019-12-24 04:50:11
问题 I have the following code to convert my JSON dataset to html table. I want to know if it is the fastest method, or should I use jqote2 with jquery to write template? Requirements: can change col definitions with a click (client can change how to view table, col definition array will change, and table can be rebuilt) sorting, filter & pagination (I believe raw data can be sorted and table can be rebuilt) conversions (If say 1 col contains data of length in different units, than a new col in

How do I use transclusion in angularjs?

由 左心房为你撑大大i 提交于 2019-12-23 13:15:55
问题 In the John Lindquist tutorial, transclusion is used to grab some content from the directive and put it in a desired place. But the docs talk about translude function and passing it to controller and compile function. So, what is transclusion and how do I use it? 回答1: When creating a basic directive, transclusion is easy: module.directive( 'myTransDir', function () { return { transclude: true, scope: true, replace: true, template: '<div><h1>Hello!</h1><div ng-transclude></div></div>', }; });

Explain this confusing dojo tutorial syntax for declare

由 我们两清 提交于 2019-12-22 06:32:36
问题 I am reading the syntax for using dojo's declare for class creation.

ClassName The className argument represents the name of the class, including the namespace, to be created. Named classes are placed within the global scope. The className can also represent the inheritance chain via the namespace. Named Class // Create a new

由 懵懂的女人 提交于 2019-12-21 15:40:30
问题 I have a main app view, with a filter menu in the header. When it's clicked, I want to filter content in a seperate news-feed view. But I don't know how to bind events (and pass class data) from clicks in one view to a function in another. How can I accomplish this? 回答1: There are a number of ways to accomplish this, but probably you want to create a model object, which is shared between the two views. Then on 'click' in view one, update the model object, and bind 'on change' in view two to

angularjs : logging scope property in directive link function displays undefined

由 坚强是说给别人听的谎言 提交于 2019-12-21 09:13:37
问题 I have this basic plnkr which just implements a basic "Hello, X" directive. In the link function I am logging scope.name but I get undefined ? Why is it so?

There is a pull request open to change this issue but it is not clear if this one is going to be merged. In the meantime a way of getting an interpolated value is by

I am not able to understand how jQuery chaining works [closed]

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . I am not able to understand how jQuery chaining works. jQuery("div").attr("id", "_id") .hide() .show(); I did something like chaining, but I'm not sure if it's the same logic that jQuery uses. var fun = (function
