Creating The Interface

This is where we will create a simple interface for our application. This code will only display the html form inputs and div content for your post result. To create this simply copy and write it into your text editor, then save it as index.html. 
  1. <!DOCTYPE hmtl>
  2. <html lang="en">
  3. 	<head>
  4. 		<meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
  5. 		<link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
  6. 	</head>
  7. <body>
  8. 	<nav class="navbar navbar-default">
  9. 		<div class="container-fluid">
  10. 			<a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
  11. </a>		</div>
  12. 	</nav>
  13. 	<div class="col-md-3"></div>
  14. 	<div class="col-md-6 well">
  15. 		<h3 class="text-primary">How to Create a Post in your Page</h3>
  16. 		<hr style="border-top:1px dotted #ccc;"/>
  17. 		<div class="col-md-8">
  18. 			<div class="alert alert-info">NEWSFEED</div>
  19. 			<div id="result"></div>
  20. 		</div>
  21. 		<div class="col-md-4">
  22. 			<form>
  23. 				<div class="form-group">
  24. 					<label>Name</label>
  25. 					<input type="text" id="name" class="form-control" />
  26. 				</div>
  27. 				<div class="form-group">
  28. 					<label>Content</label>
  29. 					<textarea id="content" class="form-control" style="resize:none; height:150px;">
  30. 					</textarea>
  31. 				</div>
  32. 				<center><button type="button" class="btn btn-primary" onclick="postToPage();">Post</button></center>
  33. 			</form>
  34. 		</div>
  35. 	</div>
  36. <script src="script.js"></script>	
  37. </body>	
  38. </html>

Creating JavaScript Function

This is where the main function of the application is. This code will allow you to post a content when submit the form inputs. To do this just copy and write these block of codes inside the text editor and save it as script.js. 
  1. function postToPage(){
  2. 	var name=document.getElementById('name').value;
  3. 	var content=document.getElementById('content').value;
  4.  
  5. 	if(name =="" || content ==""){
  6. 		alert("Please enter something first!");
  7. 	}else{
  8. 		var parent=document.createElement('div');
  9. 		var el_name=document.createElement('h5');
  10. 		var el_message=document.createElement('p');
  11. 		var el_line=document.createElement('hr');
  12. 		var txt_name=document.createTextNode(name);
  13. 		var txt_message=document.createTextNode(content);
  14. 		el_name.appendChild(txt_name);
  15. 		el_message.appendChild(txt_message);
  16. 		el_line.style.border='1px solid #ccc';
  17. 		parent.appendChild(el_name);
  18. 		parent.appendChild(el_line);
  19. 		parent.appendChild(el_message);
  20. 		parent.setAttribute('class', 'well');
  21. 		document.getElementById('result').appendChild(parent);
  22.  
  23. 		document.getElementById('name').value="";
  24. 		document.getElementById('content').value="";
  25. 	}
  26.  
  27. }

In the code provided we just only create one method called postToPage(). This function will display the data you have been submitted from the forms. The function use a simple trick that will allow you to display your post content. We use a function called createElement(), this will dynamically create a new element. Then we use createTextNode() function that will create a new text for your newly create element, and last we will use the appendChild() that will append the contents to the targeted div element.
