PHP 5.5/PHP5.6/PHP-NG and HHVM which has better performance?
Abstract: In a Vagrant-based local environment, the HHVM test results may be poor due to an error. With the help of HHVM partners, this cause is still being studied! However, in a 4 GB Virtual Machine in DigitalOcean, HHVM even overwrites the latest PHP-NG!
Conclusion: they reflect better performance of HHVM (after JIT hot boot), although for som
When we use ng-options, we may find that the first item in the drop-down list is empty after rendering is complete, and after we select an item, the first item that is empty is gone, so the user experience is bad.The reason is that when we use ng-options, we use it in conjunction with the Model directive Ng-model, so that we can know that the first item generated

AngularJS uses the ng-repeat command to implement the drop-down box. angularjsng-repeat
Ng-repeat of AngularJs allows us to easily traverse arrays to generate Dom elements, but improper use may also cause performance problems. We will share with you the use of the ng-repeat command in the project implementation drop-down box.

When writing HTML documents, in order to implement the Code modularity, to increase the code readability and maintainability of complex pages, we often think of spreading the code into different HTML filesAngularjs inside the ng-include command combined with Ng-controller can be very convenient to achieve this purposeThe ng-include directive is used to include ex
1. A single page will automatically load the first Ng-app2. If you want to start another ng-app, you need to start with the red part of the code below, and then start 2 Ng-app3. Special note: The red part of the code must be put in the end , for example, can not be placed before the blue code , or error4. A ng-app can
Practice Angularjs's Ng-change event today.For example, when the user makes a choice, there is no user-appropriate option in the options specified by the system. At this point we can let the user fill out.The first text box is hidden. It is not displayed until the user selects a checkbox.The value of IsVisible in the model of the ANGULARJS program is false.This way, when the program is running, the text box is hidden.Next, I need to add a checkbox to

Previous blog (iii) the use of Ng-app and the automatic loading of the ANGULARJS framework presented the use of Ng-app directives. It was strange to think of the 4th and 5th cases, because we saw only the phenomenon and didn't see the essence. JS error, the most intuitive way to behave is: pop up a very unfriendly JS error window. The browser will not pop up the error message when the script has an uncaught
Depressed! How to solve the problem of getting the value bound to ng-model in ionic as undefined? ionicng-model
When ng-model is used in ionic today, the value is undefined in the corresponding controller. I used to get it when I used angularjs's ng-model binding. This is embarrassing and I decided to check it out. Let's take a look at the following demo.

Method:
1. Make sure that your wireless connection is Enabled: ifconfig checks whether wlan0 is enabled or other wireless adapters are enabled. If not, the subsequent steps cannot be performed.
You can use ifconfig-a to check whether there is a wireless adapter, and then run the ifconfig wlan0 up command to start the wireless adapter (wlan0 is the name of the wireless adapter found in ifconfig-)
2. Enable the NIC to be in the listening mode:

When you minify your code with a tool like uglify, the resulting minified file would rename variables. This was a problem for ANGUALRJS, which uses parameter names to provide injected dependencies. You could use the array notation manually, but no human shouldever has to suffer this fate, or do could use Ng -annotate with Grunt, and let your helper robots get the job done instead.Without annotations:Angular.module ("mymod").
