The removeTokens() method of p5.Table in p5.js is used to remove all the specified characters from values in the table. A specific column can be specified for removing the token from only that column. However, if no column is specified then the values of all the columns and rows in the table are processed.
Syntax:
removeTokens( chars, [column] )
Parameters: This function accepts two parameters as mentioned above and described below:
- chars: It is a String that specifies all the characters that have to be removed.
- column: It is a String or integer that specifies the column name or ID of the column to be trimmed. It is an optional parameter.
The example below illustrates the removeTokens() method in p5.js.
Example 1:
function setup() {   createCanvas(500, 300);   textSize(16);     tokensInput = createInput();   tokensInput.position(30, 40)     trimBtn =     createButton("Remove specified tokens");   trimBtn.position(30, 80);   trimBtn.mouseClicked(cleanTableData);     // Create the table   table = new p5.Table();     // Add two columns   table.addColumn("subject");   table.addColumn("performance");     // Add some rows to the table   let newRow = table.addRow();   newRow.setString("subject",                    "----Maths---");   newRow.setString("performance",                    "====Good===");     newRow = table.addRow();   newRow.setString("subject",                    "  English");   newRow.setString("performance",                    "__-Excellent--");     newRow = table.addRow();   newRow.setString("subject",                    "Science");   newRow.setString("performance",                    ",,, ;;OK;");     showTable(); }   function cleanTableData() {   let tokensToRemove = tokensInput.value();     // Remove given tokens only from the   // whole table   table.removeTokens(tokensToRemove);     // Redraw the table   showTable(); }   function showTable() {   clear();     // Display the rows present in the table   for (let r = 0; r < table.getRowCount(); r++)     for (let c = 0; c < table.getColumnCount(); c++)       text(table.getString(r, c),            20 + c * 100,            140 + r * 20);         text("Enter the tokens that have to be" +            " removed from the table values",            20, 20); } |
