How to implement Jquery.data ()The role of Jquery.data () is to append data to a normal object or DOM Element.The following is a three-part analysis of the de facto approach:1. Append data to the object with name and value, that is, pass in three parameters, the first parameter is the object that needs additional data, the second parameter is the name of the data, and the third parameter is the value of the data.Of course, the only way to get a value is to not pass in the third argument.2. Appen

referenced when the custom form is designed and saved. ThenWhen the form is running, it parses the settings and calls the method provided by FusionCharts to display the image. The specific parsing process encapsulates a common method. You can call this method in Form Design to display various graphs based on the data. The encapsulation method is as follows: Function ShowOneGraph (obj ){ Var iWidth = obj.

if is one of the longest used judgments in all programming languages, but in JS, what can be used in the if Chinese as the judgment expression? For example, how many lines, just missing a parenthesis, true and false is completely different, what does it mean? var obj={}; Obj. Funtext=function () {}; if (obj. Funtext) { alert ("True

Detailed description of attribute descriptors in ECMAScript 5 and ecmascript Attribute descriptor is a new concept in es5. its function is to add more control over the attributes of an object. Object. defineProperty To study attribute descriptors, first talk about the Object. defineProperty method. This method defines new attributes for the object or modifies existing attributes. The prototype is as follows:Copy codeThe Code is as follows:Object. defineProperty (

string parameter that represents the property name that is used to determine whether the property is in the current object instance, rather than in the object's prototype chain. Let's take a look at the following example: var arr = []; Console.log (Arr.hasownproperty ("Length"));//true Console.log (Arr.hasownproperty ("hasOwnProperty")); False In this example, first by defining an instance of an array object arr, we know that the array object actually inherits the object throug

. Hey.. How to register a component: At the command prompt, enter "regsvr32 [DLL path]". Image add watermark is simply to get the picture size, and then write the watermark up. The ASP code is just a control component. Use code to explain everything. One: Get the picture size (here is the pixel value). All the friends who are learning Photoshop should understand. Copy Code code as follows: Set Obj=server. CreateObject ("Wsimage.resize"

until the data member is assigned a value. A data member can To be an integer, an array, an associated array (associative array), or an object. method is defined as a function form in a class, you should use $this->name when accessing a class member variable in a method, otherwise it can only be a local variable for a method. To create an object using the new operator: $obj =new something; You can then use the member function to pass: $
