this week's study Array of pointers can hold multiple character arrays, each element in the pointer array is the first address of a character array, and the pointer array name is a level two pointer A pointer to a pointer that represents a second-level pointer The malloc () function can define dynamic memory to avoid wasted memory and finally free up memory with Learning experience This week to learn to build a project, which is more difficult than the PTA on the

Today, the interview, was asked some questions about JS, can only say that their scope is limited, do not notice these aspects, now take out to share, hope that later can learn more fresh knowledge to enrich themselves! How can i solve my own page without being nested? Very simple lines of code can solve such problems; Add such a section of JavaScript code to the These lines of code are guaranteed to work.

We are writing HTML page or JSP page is, sometimes need to use the IFRAME tag in one page nested another page, and two pages some data need to interact, this time will use JS technology, call each other method, When we need to invoke the JS method in the child page embedded in the IFrame tab in the parent page, you can use: document.getElementById (the ID of the IFRAME). Contentwindow.childtest (); Note: The ID of the IFRAME: refers to the ID of the

Problem In Android development, there is a problem, is ListView nested GridView , you need to click the whole ListView Item to jump. However, GridView you cannot jump the page when you click on the area. This is because the GridView focus has been gained. Causes the click to not jump. The solution is: 1. Add the outermost layer of the item Android:descendantfocusability= "Blocksdescendants" 2. Add in Adapter Holder.mGridView.setClickab

Nested functions (Scope chain) When you are nesting a function, be aware that the actual scope chain is changing, which may not seem intuitive. You can put the following code into the Firebug monitoring value changes. Copy Code code as follows: var testvar = ' Window property '; var O1 = {testvar: ' 1 ', fun:function () {alert (' O1: ' +this.testvar+ ' var O2 = {testvar: ' 2 ', fun:function () {alert (' O2: ' +this.testvar ';}}; O1
