easyui tree 的onClick事件该怎么调用？

用firebug查看其生成html，发现其checkobx是假的，只是一个span，来回的变样式而已，汗

-->$(".tree-checkbox", tree).unbind(".tree").bind("click.tree", function() {

if ($(this).hasClass("tree-checkbox0")) {

$(this).removeClass("tree-checkbox0").addClass("tree-checkbox1");

} else {

if ($(this).hasClass("tree-checkbox1")) {

$(this).removeClass("tree-checkbox1").addClass("tree-checkbox0");

} else {

if ($(this).hasClass("tree-checkbox2")) {

$(this).removeClass("tree-checkbox2").addClass("tree-checkbox1");

}

}

}

_2eb($(this).parent());

_2ec($(this).parent());

return false;

});

然后再看其onClick事件脚本

-->$(".tree-node", tree)

....

bind("click.tree", function() {

$(".tree-node-selected", tree).removeClass("tree-node-selected");

$(this).addClass("tree-node-selected");

if (opts.onClick) {

var _2ea = this;

var data = $.data(this, "tree-node");

opts.onClick.call(this, );

}

})

相应的修改其check脚本

$(".tree-checkbox", tree).unbind(".tree").bind("click.tree", function() {

if ($(this).hasClass("tree-checkbox0")) {

$(this).removeClass("tree-checkbox0").addClass("tree-checkbox1");

} else {

if ($(this).hasClass("tree-checkbox1"))
