Manipluating HTML Forms with WebRenderer

HTML Form manipulation is a fairly straight forward task with WebRenderer. It involves using the IBrowserCanvas method executeScript which allows you to get direct access through JavaScript to HTML Forms on the page.

The HTML Form manipulation example textfield takes a String of the text that you wish to enter into the HTML textfield. There is an "AutoForm" JButton to add the Java textfield value to the HTML form. There is also a Submit Form JButton to submit the HTML form.

The key code in this example:

    // Getting a reference to the documents html form, getting reference to the elements
    String javascript = "var form=document.forms[0];"+"var elms=form.elements;" + "elms.length;";
    // Getting the number of elements from elms.length for the html form
    int num = (new Integer(browser.executeScriptWithReturn(javascript))).intValue();
              for (int i=0; i< num; i++) {
                       // Loop through getting each elements name, value and type
                       javascript = "elms["+i+"].name;";
                      String name = browser.executeScriptWithReturn(javascript);
                       javascript = "elms["+i+"].value;";
                       String value = browser.executeScriptWithReturn(javascript);
                       javascript = "elms["+i+"].type;";
                       String type = browser.executeScriptWithReturn(javascript);
                       System.out.println("For Element "+i+" the Name is: "+name+" and value is: "+value+" and type is: "+type);
                        // If the type is a textfield we will set the value to WebRenderer
                        javascript = "if (elms["+i+"].type=='text')elms["+i+"].value='My Value for the HTML textfield';";
                        // Executing the script on the browser to set the textfield with the value

    // Constructing a form.submit JavaScript call
    String javascript = "form.submit()";
    // Executing the JavaScript on the browser

This example will work on all platforms.
