How Can jQuery Simplify Converting JSON Data into HTML Tables?

jQuery's Simplified Approach to JSON to HTML Table Conversion

Converting JSON arrays into HTML tables can be a tedious task, but jQuery simplifies the process dramatically.

To generate a table from a JSON array, use the getJSON() function to retrieve the data:

$.getJSON(url , function(data) {

Next, create the table body:

var tbl_body = "";

Iterate over the JSON array rows and columns to create the table cells:

$.each(data, function() {
    var tbl_row = "";
    $.each(this, function(k , v) {
        tbl_row += "<td>"+v+"</td>";
    });

Exclude specific fields by adding an object to check for the keys to be omitted:

var expected_keys = { key_1 : true, key_2 : true, key_3 : false, key_4 : true };

Add the if condition to check for keys to be excluded:

if ( ( k in expected_keys ) && expected_keys[k] ) {
...
}

Append the table body to the target HTML element:

$("#target_table_id tbody").html(tbl_body);

Alternatively, for improved security, use the injection-free version below:

$.getJSON(url , function(data) {
    var tbl_body = document.createElement("tbody");
    var odd_even = false;
    $.each(data, function() {
        var tbl_row = tbl_body.insertRow();
        $.each(this, function(k , v) {
            var cell = tbl_row.insertCell();
            cell.appendChild(document.createTextNode(v.toString()));
        });        
    });            
    $("#target_table_id").append(tbl_body);   
});
