使用document.body.appendChild附加整个代码块?

如果您使用的是纯JavaScript,您可以使用以下内容:

var body = document.body;
body.innerHTML += 'Whatever you want to append.';

function addLABjs(callback) {
    var script = document.createElement("script");
    script.setAttribute("src", "YourOtherScript.js");
    script.addEventListener('load', function () {
        var script = document.createElement("script");
        script.textContent = "(" + callback.toString() + ")();";
        document.body.appendChild(script);
    }, false);
    document.body.appendChild(script);
}

// the guts of this userscript


function main() {
    $LAB.script("YourOtherScript.js").wait()
        .script("YourOtherScript.js")
        .script("YourOtherScript.js").wait();

    $(document).ready(function () {
    });
}

addLABjs(main);
