Protect / Secure your Website Content using jQuery

Now a days website owners want to protect their content from copiers. In order to avoid Plagiarism, it is very necessary to make sure the Content, Source and Images from their site is not copied.

I wrote a simple jQuery code that will protect your content from copying text, dragging images, viewing source, & disables the link which having image paths.

jQuery Code

function secure() {

    document.onkeypress = function (e) {

        e = e || window.event;

        if (e.keyCode === 123) {

            return false

        }

    };

    document.onmousedown = function (e) {

        e = e || window.event;

        if (e.keyCode === 123) {

            return false

        }

    };

    document.onkeydown = function (e) {

        e = e || window.event;

        if (e.keyCode === 123) {

            return false

        }

    };

    document.oncontextmenu = t;

    document.onmouseup = t;

    var n = false;

    var r = false;

    var i = false;

    window.onkeyup = function (e) {

        if (e.which === 17) n = false

    };

    window.onkeydown = function (e) {

        if (e.which === 17) n = true;

        if ((e.which === 85 || e.which === 65 || e.which === 88 || e.which === 67 || e.which === 86 || e.which === 83) && n === true) {

            return false

        }

    };

    window.onkeyup = function (e) {

        if (e.which === 93 || e.which === 91 || e.which === 224) i = false

    };

    window.onkeydown = function (e) {

        if (e.which === 17 || e.which === 93 || e.which === 91 || e.which === 224) i = true;

        if ((e.which === 85 || e.which === 65 || e.which === 88 || e.which === 67 || e.which === 86 || e.which === 83) && i === true) {

            return false

        }

    };

    document.ondragstart = t;

    e("a").each(function (t, n) {

        var r = n.href;

        if (/\.(jpg|png|gif)$/.test(r)) {

            e(this).prop("href", "#")

        }

    })

}
