Creating JavaScript Function
This is where the main function of the application is. This code will dynamically randomize the table content when the button is clicked. To do this just copy and write these block of codes inside the text editor and save it as script.js.
- function
shuffleArray(
array)
{
- var
temp =
[
]
;
- var
len=
array.length
;
- while(
len)
{
- temp.push
(
array.splice
(
Math
.floor
(
Math
.random
(
)
*
array.length
)
,
1
)
[
0
]
)
;
- len--;
- }
- return
temp;
- }
- function
displayTable(
)
{
- var
firstname =
[
"John"
,
"Steve"
,
"Luke"
,
"Bruce"
]
;
- var
lastname =
[
"Smith"
,
"Wonder"
,
"Hulgan"
,
" Banner"
]
;
- var
age =
[
"38"
,
"32"
,
"31"
,
" 34"
]
;
- var
newArray1=
shuffleArray(
firstname)
;
- var
newArray2=
shuffleArray(
lastname)
;
- var
newArray3=
shuffleArray(
age)
;
- var
html=
""
;
- for
(
var
i=
0
;
i<
newArray1.length
;
i++
)
{
- html+=
"<tr><td>"
+
newArray1[
i]
+
"</td><td>"
+
newArray2[
i]
+
"</td><td>"
+
newArray3[
i]
+
"</td></tr>"
;
- }
- document.getElementById
(
'result'
)
.innerHTML
=
html;
- }
In the code above we will create a method called shuffleArray(), this function will randomize the data in array when called. The function is consist of loops that will append the data and splice it to get a random result.
