我正在尝试自动点击按钮以在加载html页面时启动功能.我已经尝试过document.getElementById('watchButton').click它似乎不起作用,按钮没有被点击.有什么建议？

<div class="content">
        <div class="action-area ch30">
            <button class="button dh" id="watchButton">Start Geolocation Watch</button>
            <button class="button dh" id="refreshButton" >Refresh Geolocation</button>
        </div>

javascript:

    run:function() {
    var that = this;
    document.getElementById("watchButton").addEventListener("click", function() {
        that._handleWatch.apply(that, arguments);
    }, false); 
    document.getElementById("refreshButton").addEventListener("click", function() {
        that._handleRefresh.apply(that, arguments);
    }, false);
},

谢谢!
