In the JavaScript code in the address bar, you can paste the following statement into the address bar and press enter to see the effect. Javascript: with (document. body) {background = ""; bgColor = "#779966"; text = "# bb4400"}; void (document. styleSheets [0]. addRule ("TD", "border: 1 solid black; background-color: # eef9ee!

The return statement for JavaScript is a simple introduction:The return statement is very important in JS, not only has the function of returning function value, but also has some special usages, it is very necessary to have a clear grasp. The following is a simple example of the return statement to explain the role.On

Declaration of variables JavaScript uses keyword var to declare a variable, you can declare it after it is assigned, or you can assign a value at the same time as a declaration, and multiple variables declare commas (,) delimited. For example: The code is as follows Copy Code Declare first, then assign a valuevar sex;sex= "Male";To assign a value while declaringvar age=22;var name= "John";Declaring multiple variables at t

Appendchildscript The modified code can be run in IE, Firefox, opera, and Safari3.0. Versions prior to Safari3.0 do not correctly support the Text property, but allow the use of text node technology to specify code. If you need to be compatible with earlier versions of Safari, you can use the following

equal to 5 o'clock, the value of num is exactly 55.Continuevar num = 0; outermost: for (var i=0; ) { for ( var j=0; J ) { if (i = = 5 j = 5) { continue outermost; } num++ ; // theIn this case, the continue statement forces the continuation of the loop--exiting the inner loop and executing the outer loop. When J is 5 o'clock, the Continue statement executes, which means

Today I learned the For loop in JavaScript and the judgment statement for iffor (initial value; loop condition; action) {Code statements that meet the criteria to execute}Initial value: The initialization variable before the loop, usually an assignment expression: it is recommended to assign a value with Var, which can speed up the operation.Loop condition: The condition to be evaluated before each loop, is

Possible results A = B;a = OBJ.B;OBJ.A = B;OBJ.A = obj.b; The 1th part uses the WITH statement, part 2nd is an equivalent statement that does not use the WITH statement, and the 3rd part is the final possible result, and if only from the WITH stat
