JSON HTML

3 min read

JSON can very easily be translated into JavaScript.

JavaScript can be used to make HTML in your web pages.

HTML Table #

Make an HTML table with data received as JSON:

Example #

obj = { table: "customers", limit: 20 }; dbParam = JSON.stringify(obj); xmlhttp = new XMLHttpRequest(); xmlhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { myObj = JSON.parse(this.responseText); txt += "<table border='1'>" for (x in myObj) { txt += "<tr><td>" + myObj[x].name + "</td></tr>"; } txt += "</table>" document.getElementById("demo").innerHTML = txt; } } xmlhttp.open("POST", "json_demo_db_post.php", true); xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); xmlhttp.send("x=" + dbParam);

Dynamic HTML Table #

Make the HTML table based on the value of a drop down menu:

<select id="myselect" onchange="change_myselect(this.value)"> <option value="">Choose an option:</option> <option value="customers">Customers</option> <option value="products">Products</option> <option value="suppliers">Suppliers</option> </select> <script> function change_myselect(sel) { var obj, dbParam, xmlhttp, myObj, x, txt = ""; obj = { table: sel, limit: 20 }; dbParam = JSON.stringify(obj); xmlhttp = new XMLHttpRequest(); xmlhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { myObj = JSON.parse(this.responseText); txt += "<table border='1'>" for (x in myObj) { txt += "<tr><td>" + myObj[x].name + "</td></tr>"; } txt += "</table>" document.getElementById("demo").innerHTML = txt; } }; xmlhttp.open("POST", "json_demo_html_table.php", true); xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); xmlhttp.send("x=" + dbParam); } </script>

HTML Drop Down List #

Make an HTML drop down list with data received as JSON:

Example #

obj = { table: "customers", limit: 20 }; dbParam = JSON.stringify(obj); xmlhttp = new XMLHttpRequest(); xmlhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { myObj = JSON.parse(this.responseText); txt += "<select>" for (x in myObj) { txt += "<option>" + myObj[x].name; } txt += "</select>" document.getElementById("demo").innerHTML = txt; } } xmlhttp.open("POST", "json_demo_html_table.php", true); xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); xmlhttp.send("x=" + dbParam);
