     concat method is used to join two or more arrary or strings. This method does not change the existing(old) value, but return the joined value(new value). Syntax string1.concat(string2); or array1.concat(array2); Example 1 var str1="Allinworld"; var str2="99"; alert(str1.concat(str2)); Example 2  var ar1 = ["A","B","C"];  var ar2 = ["D","E","F"]; alert(ar1.concat(ar2)); Example Program:- (Editor) Editor is Loading...

          Return the selected value from string, we can select the string value by using index. If the specified index value is outof range then it will return the -1. slice() method for array values Syntax      string.slice(startindex[,endindex]);   endindex is the optional. Example str="Merbin joe" ; alert(str.slice(3));   //return from 3rd character ["bin joe"] alert(str.slice(3,5)); //return 3 to 5th character ["bi"] Example Program:- (Editor) Editor is Loading...

     Return the selected value from array, we can select the array value by using index. If the specified index value is out of range then it will return the -1. slice() method for string values Syntax      string.slice(startindex[,endindex]);  endindex is the optional. Example : var fruits = ["Jan", "Feb", "Mar", "Apr", "May"]; alert(fruits.slice(1)); //return 2 to 5th value  (Not removed) alert(fruits.slice(2,4));  //return 3 to 4th value Example Program:- (Editor) Editor is Loading...

     In javascript we can call a function while clicking html elements in three types, they are define in following example. 1) onclick 2) object.onclick 3) addEventListener 1) onclick:      This is type is define inside the html tag. When you want to call a function in while clicking you can use the onclick attribute inside the html elements. Syntax <element onclick="script or function calling"> Example <script>  function cl_fun() {   alert("Function Called"); } </script>   <input type="button" onclick="cl_fun();" value="Click Here"> 2) object.onclick      In this method we are call a function using html elements id. Syntax var obj=document.getElementById("element_id"); obj.onclick=function(){/*script here*/}; Example <script>  var obj=document.getElementById("btnid");  obj.onclick=function(){alert("Function Called");}; or  var obj=document.getElementById("btnid...

     In this section we are going to see how to convert the pure html and css code to pdf using itextsharp and itexsharp.xmlworker dll's. Download itextsharp.xmlworker.dll Downlaod itextsharp.dll Note:      You should use the same version of the itextsharp.dll and itextsharp.xmlworker.dl If you not use the same version you will see like the following error.  Server Error in '/' Application.

     The Boolean() constructor function takes one parameter to be converted to a boolean value (i.e., true or false). Any valid JavaScript value that is not 0, −0, null, false, NaN, undefined, or an empty string(""), will be converted to true. Below, we create two boolean object values. One true, one false. ""   => empty string returns false value "any val"   => string returns true value 3<4    => returns true 4<3   => returns false null  => returns false Syntax      Boolean(condition); Example      alert(Boolean(3>4)); Example Program:- (Editor) Editor is Loading... Output:- Advertisement Tags: Boolean() method in allinworld99, Boolean() method will return true or false value

     If the condition is true the if statements are executed otherwise the next statement will execute. Syntax      if(condition)      {         Statements;      } Flow chart Example    if(10<50)    {       alert("Executed");    } Example Program:- (Editor) Editor is Loading... Output:- Advertisement Tags: if statement in javascript allinworld99, if statement in java allinworld99, if statement in c, if statement in cpp, if flow chart in allinworld99,

      if...else is used to check the condition and if the condition is true the if part statements are executed and if the condition is false the else part statements are executed. Syntax   if(condition)   {      Statements;   }   else   {      Statements;   } Flow Chart: Example: if(10<5) {    alert("5 is big"); } else {    alert("10 is big"); } Example Program:- (Editor) Editor is Loading...

     The if...Then...else statement is fundamental to many programming languages. In Intent language, this statement can appear in several different forms.      allinworld99 recommended you to learn logical wise concept. Syntax    if(condition)   {     statements;   }   else if(condition)   {     statements;   }   else  {     statements;   } Flow Chart: Example: if(6<10) {    alert("10 is big"); } else if(10<15) {    alert("15 is big"); } else {    alert("No condition matched"); } Example Program:- (Editor) Editor is Loading... Output:- Advertisement Tags: if else if then else in allinworld99, allinworld99 in if else if then else

      A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case, and the variable being switched on is checked for each switch case. Syntax switch(expression) {   case condition_variable-1:           statements;           break;   case condition_variable-2:           statements;           break;   case condition_variable-3:           statements;           break;       --------------       --------------       --------------   case condition_variable-n:           statements;           break; default:            statements; } Example a=3; switch(a) case 1: {       alert("One");       br...

Why For Loops? 1) Like all loops, "for loops" execute blocks of code over and over again. 2) The advantage to a for loop is we know exactly how many times the loop will execute before the loop starts. Syntax for(initialization; condition; increment/decrement) {   Statements; } Example: for(i=0;i<=5;i++) {   statements; } Flow chart of for loop:       In the following flowchart is draw similar to the above example, don't forget to see the whole explanation about the flowchart. Step 1:      Start  Initialization, if you want to initialize  any value you can assign here this is optional . Step 2:      Conditions are return true or false value this also optional, some examples are Conditions 3>5        => return False 6<=6     =>  return True 3==3     =>  return True Symbols <           => Less than >     ...
