Introduction

In today's digital age, search functionality is a crucial aspect of any web application. When it comes to SharePoint 2010, creating a search field that allows users to find specific keywords on a long page can be a daunting task. However, with the help of JavaScript and jQuery, we can create a custom search field that mimics the Ctrl-F functionality. In this article, we will explore how to create a permanent search field that allows users to search for keywords on a SharePoint 2010 page.

Understanding the Problem

The target group for this project is users who are unable or unwilling to learn how to use the Ctrl-F function to search for keywords on a page. This means that we need to create a custom search field that is easy to use and provides a seamless search experience. The search field should be able to highlight the search results on the page, making it easy for users to find the information they need.

Creating the Search Field

To create the search field, we will use jQuery to add a text input field to the page. We will also use JavaScript to handle the search functionality. Here is the code to create the search field:

<input type="text" id="search-field" placeholder="Search...">
<button id="search-button">Search</button>

We will add a button next to the search field to trigger the search functionality. When the button is clicked, we will use JavaScript to get the search query from the text input field and highlight the search results on the page.

Highlighting Search Results

To highlight the search results, we will use a combination of JavaScript and CSS. We will create a function that takes the search query as an argument and highlights the search results on the page. Here is the code to highlight the search results:

function highlightSearchResults(query) {
  // Get all the elements on the page
  var elements = document.getElementsByTagName('*');

  // Loop through each element
  for (var i = 0; i < elements.length; i++) {
    // Get the text content of the element
    var text = elements[i].textContent;

    // Check if the text content contains the search query
    if (text.toLowerCase().indexOf(query.toLowerCase()) !== -1) {
      // Highlight the search result
      elements[i].style.backgroundColor = 'yellow';
    }
  }
}

We will also add a CSS rule to style the highlighted search results:

.highlighted {
  background-color: yellow;
}

Triggering the Search Functionality

To trigger the search functionality, we will add an event listener to the search button. When the button is clicked, we will get the search query from the text input field and call the highlightSearchResults function. Here is the code to trigger the search functionality:

$('#search-button').click(function() {
  var query = $('#search-field').val();
  highlightSearchResults(query);
});

Adding a Clear Button

To add a clear button to the search field, we will create a new button and add an event listener to it. When the clear button is clicked, we will clear the search query from the text input field and remove the highlighted search results from the page. Here is the code to add a clear button:

<button id="clear-button">Clear</button>

We will also add an event listener to the clear button:

$('#clear-button').click(function() {
  $('#search-field').val('');
  $('.highlighted').removeClass('highlighted');
});

Conclusion

In this article, we have explored how to create a custom search field that mimics the Ctrl-F functionality. We have used jQuery to add a text input field and a button to the page, and JavaScript to handle the search functionality. We have also used CSS to style the highlighted search results. With this custom search field, users can easily search for keywords on a SharePoint 2010 page without having to learn how to use the Ctrl-F function.

Example Use Case

Here is an example use case for the custom search field:

Suppose we have a long page on SharePoint 2010 that contains information about a company's products. The page contains a list of products, each with a description and a price. The user wants to find a specific product on the page, but they are unable or unwilling to learn how to use the Ctrl-F function. They can use the custom search field to search for the product name or description. When they click the search button, the search field will highlight the search results on the page, making it easy for the user to find the information they need.

Code Snippet

Here is a code snippet that demonstrates the custom search field:

<input type="text" id="search-field" placeholder="Search...">
<button id="search-button">Search</button>
<button id="clear-button">Clear</button>

<script>
  $('#search-button').click(function() {
    var query = $('#search-field').val();
    highlightSearchResults(query);
  });

  $('#clear-button').click(function() {
    $('#search-field').val('');
    $('.highlighted').removeClass('highlighted');
  });

  function highlightSearchResults(query) {
    var elements = document.getElementsByTagName('*');
    for (var i = 0; i < elements.length; i++) {
      var text = elements[i].textContent;
      if (text.toLowerCase().indexOf(query.toLowerCase()) !== -1) {
        elements[i].style.backgroundColor = 'yellow';
      }
    }
  }
</script>

CSS Rule

Here is a CSS rule that styles the highlighted search results:

.highlighted {
  background-color: yellow;
}
