Getting Started with JavaScript(ES5)

The Essential JS 2 for JavaScript (global script) is an ES5 formatted pure JavaScript framework which can be directly used in latest web browsers.

Control Initialization

The Essential JS 2 JavaScript controls can be initialized by using either of the following ways.

  • Using local script and style references in a HTML page.
  • Using CDN link for script and style reference.

Using local script and style references in a HTML page

Step 1: Create an app folder quickstart for getting started.

Step 2: You can get the global scripts and styles from the Essential Studio JavaScript (Essential JS 2) build installed location.

Syntax:

Script: **(installed location)**/Syncfusion/Essential Studio/{RELEASE_VERSION}/Essential JS 2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Style: **(installed location)**/Syncfusion/Essential Studio/{RELEASE_VERSION}/Essential JS 2/{PACKAGE_NAME}/styles/material.css

Example:

Script: C:/Program Files (x86)/Syncfusion/Essential Studio/16.3.29/Essential JS 2/ej2-query-builder/dist/global/ej2-querybuilder.min.js

style: C:/Program Files (x86)/Syncfusion/Essential Studio/16.3.29/Essential JS 2/ej2-buttons/styles/material.css

The Custom Resource Generator (CRG) is an online web tool, which can be used to generate the custom script and styles for a set of specific controls. This web tool is useful to combine the required control scripts and styles in a single file.

Step 3: Create a folder ~/quickstart/resources and copy/paste the global scripts and styles from the above installed location to ~/quickstart/resources/package corresponding package location.

Step 4: Create a HTML page (index.html) in ~/quickstart/index.html and add the Essentials JS 2 script and style references.

Step 5: Now, add the Query Builder and initiate the Syncfusion JavaScript (ES5) Query Builder control in the ~/quickstart/index.html by using following code

        <!-- Essential JS 2 query-builder material theme (Control Styles) -->

        <!-- Essential JS 2 query-builder global script (Control Script) -->
        <script src="resources/querybuilder/ej2-querybuilder.min.js" type="text/javascript"></script>
    </head>
    <body>
        <!-- Add the HTML div element  -->
        <div id="querybuilder" class="row">
        <script>
        var columnData = [
            { field: 'EmployeeID', label: 'Employee ID', type: 'number' },
            { field: 'FirstName', label: 'First Name', type: 'string' },
            { field: 'TitleOfCourtesy', label: 'Title Of Courtesy', type: 'boolean', values: ['Mr.', 'Mrs.']},
            { field: 'Title', label: 'Title', type: 'string' },
            { field: 'HireDate', label: 'Hire Date', type: 'date', format: 'dd/MM/yyyy' },
            { field: 'Country', label: 'Country', type: 'string' },
            { field: 'City', label: 'City', type: 'string' }
        ];
        var qryBldrObj = new ej.querybuilder.QueryBuilder({
            width: '70%',
            columns: columnData,
        });
        qryBldrObj.appendTo('#querybuilder');
        </script>
    </body>
</html>

Step 6: Now, run the index.html in web browser, it will render the Syncfusion JavaScript Query Builder control.

Step 1: Create an app folder quickstart for getting started.

Step 2: The Essential JS 2 controls’s global scripts and styles are already hosted in the below CDN link formats.

Syntax:

Dependency Script: http://cdn.syncfusion.com/ej2/{DEPENDENCY_PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Control Script: http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Dependency Styles: http://cdn.syncfusion.com/ej2/{DEPENDENCY_PACKAGE_NAME}/styles/material.css

Control Styles: http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/styles/material.css

Example:

Script: http://cdn.syncfusion.com/ej2/ej2-querybuilder/dist/global/ej2-querybuilder.min.js

Styles: http://cdn.syncfusion.com/ej2/ej2-querybuilder/styles/material.css

Step 3: Create a HTML page (index.html) in ~/quickstart/index.html location and add the CDN link references. Now, add the Query Builder and initiate the Syncfusion JavaScript (ES5) Query Builder control in the index.html by using following code.

                qryBldrObj.appendTo('#querybuilder');
            </script>
       </body>
  </html>

Step 4: Now, run the index.html in web browser, it will render the Syncfusion JavaScript Query Builder control.

Rendering with rule

Now, add the Query Builder and initiate the Syncfusion JavaScript (ES5) Query Builder control with rule in the ~/quickstart/index.html by using following code
