Blocks

"Ad Blocker Alert" displays a pop-up window if there is an Ad Blocker active in the browser, and limit the access to the page's content.

Message to display:

Your browser uses an Ad Blocker that prevents the correct functioning of this page.

The block includes the xe_open_exchange_rates operation whose parameter is a plain object with the following properties:

• from: a three letters currency code. For example: USD (required)
• to: a three letters currency code. For example: GBP (required)
• field: a valid jQuery selector of an input tag for assigning the exchange rate. For example, if you are using the calculated fields form plugin, and you want to assign the exchange rate to the fieldname1 field, the selector would be: [id*="fieldname1_"] (optional)
• callback: a function that will receive as parameter an object with all currencies codes and the corresponding exchange rates. For example: function(rates){alert(rates['EUR']);} (optional)
• url: the URL to the public website. In cases where the URL to the public website and the WordPress are different, might be require pass to the block the URL to the public website (optional)

Example:

xe_open_exchange_rates({'from': 'USD', 'to': 'EUR', 'field': '[id*="fieldname'+'1_"]'});

A specific example: Assuming there is a field in the form that calculate a service price in United State Dollars (USD), the fieldname1, and you want get the price in Euros (EUR), furthermore there is a hidde field for the exchange rate, the fieldname2. The equation to associate with the calculated field to calculate the price in Euros would be:

(function(){
xe_open_exchange_rates({'from': 'USD', 'to': 'EUR', 'field': '[id*="fieldname'+'2_"]'});
return fieldname1*fieldname2;
})()

If there is a dropdown field for selecting the currency code, the fieldname3, the equation would be:

(function(){
xe_open_exchange_rates({'from': 'USD', 'to': fieldname3, 'field': '[id*="fieldname'+'2_"]'});
return fieldname1*fieldname2;
})()

"Read CSV File" inserts a javascript block with the readcsv routine for reading an online CSV file and generate a javascript array to be used in the form:

readcsv(args);

• args:

  javascript object with the following properties:

  • url: url to the online CSV file.
  • headline: boolean (true or false), indicates if the first row in the CSV file is a headline row or not (false by default)
  • delimiter: symbol to delimit the row's columns (the comma symbol "," by default)
  • quotation: symbol for closing the textual columns (the double-quote symbol (") by default)
  • filter: plain object for filtering the CSV rows. For example, assuming that the file includes the columns names: column_a, column_b, and column_c, and you want get the rows whose column_a has the value 3, and column_b the value "qwerty", the filter object would be: {'column_a':3,'column_b':'qwerty'}
  • callback: javascript function that would be called after read the CSV file. The callback receives as parameter an javascrip array with the CSV rows.

    Every row would be a columns array, or an object (if the headline property was passed as true).

    Callbacks distributed with the block:

    populate_dropdown(selector, args): Populates a dropdown field with the CSV data. First parameter (selector), a valid jQuery selector to identify the dropdown field. Second parameter (args), plain object with two properties, "value": the column's name to use as values of the field's options, "text": the column's name to use for the texts of the field's options.

    Example:

    readcsv({'url':'http://www.websitedomain.com/file.csv', 'callback':populate_dropdown('[name="field_name"]', {'value':'column_a', 'text':'column_b'})});

    populate_input(selector, args): Populates an input (or textarea) field with the CSV data. First parameter (selector), a valid jQuery selector to identify the dropdown field. Second parameter (args), is a plain object with the property, "value": the column's name for the field's value.

    Example:

    readcsv({'url':'http://www.websitedomain.com/file.csv', 'callback':populate_input('[name="field_name"]', {'value':'column_a'})});

    Implementing your own callbacks:

    readcsv({'url':'http://www.websitedomain.com/file.csv', 'filter':{'column_a':3,'column_b':'qwerty'}, 'callback':function(csv_data){/* Your code Here*/}});

"Pie Chart" inserts a javascript block with the setPieChartBlock routine to generate pie chart into a canvas tag with the values passed as parameters:

setPieChartBlock(canvasId, values);

• canvasId: the routine requires you insert a <canvas id="canvasId"></canvas> tag in your webpage where display the chart. The id of the canvas tag should be passed as the first parameter of the routine.
• values: array of values to display in the chart. For example: [10,5,100].
  
  To display a label associated to the values, the elements in the array must be objects with the structure: {label: <text here>, value: <number here>}
  For example: [{label: 'First item', value: 10},{label: 'Second item', value: 5},{label: 'Third item', value: 100}]
  
  To specify the colors of bars, define the colors code as part of the object (if no colors are defined, the plugin will use the default colors).
  For example: [{label: 'First item', value: 10, color: '#FF0000'},{label: 'Second item', value: 5, color: '#00FF00'},{label: 'Third item', value: 100, color: '#0000FF'}]

Example:

setPieChartBlock('canvasId', [{label: 'First item', value: 10, color: '#FF0000'},{label: 'Second item', value: 5, color: '#00FF00'},{label: 'Third item', value: 100, color: '#0000FF'}]);

"Address Field" inserts an autocomplete address field integrated to Google Places.

  For example: [{label: 'First item', value: 10},{label: 'Second item', value: 5},{label: 'Third item', value: 100}]
  
  To specify the color of points, pass an object as the third parameter of the "setBubbleChartBlock" function, with the color attribute (if no color is defined, the plugin will use a color by default).

  setBubbleChartBlock('canvasId', [{label: 'First item', value: 10},{label: 'Second item', value: 5},{label: 'Third item', value: 100}],{color: '#FF0000'});

"Bar Chart" inserts a javascript block with the setBarChartBlock routine to generate bar chart into a canvas tag with the values passed as parameters:

setBarChartBlock(canvasId, values);

• canvasId: the routine requires you insert a <canvas id="canvasId"></canvas> tag in your webpage where display the chart. The id of the canvas tag should be passed as the first parameter of the routine.
• values: array of values to display in the chart. For example: [10,5,100].
