I have created an object array in JavaScript. How can I print the object array in the browser window, similar to print_r
function in PHP?
var lineChartData = [{
date: new Date(2009, 10, 2),
value: 5
}, {
date: new Date(2009, 10, 25),
value: 30
}, {
date: new Date(2009, 10, 26),
value: 72,
customBullet: "images/redstar.png"
}];
Simply stringify
your object and assign it to the innerHTML of an element of your choice.
yourContainer.innerHTML = JSON.stringify(lineChartData);
If you want something prettier, do
yourContainer.innerHTML = JSON.stringify(lineChartData, null, 4);
var lineChartData = [{
date: new Date(2009, 10, 2),
value: 5
}, {
date: new Date(2009, 10, 25),
value: 30
}, {
date: new Date(2009, 10, 26),
value: 72,
customBullet: "images/redstar.png"
}];
document.getElementById("whereToPrint").innerHTML = JSON.stringify(lineChartData, null, 4);
<pre id="whereToPrint"></pre>
But if you just do this in order to debug, then you'd better use the console with console.log(lineChartData)
.
