backbonejs router first query parameter

I am trying to add a query parameter as the first parameter in backbonejs route but no luck.

Below is my router config.

TabsRouter = Backbone.Router.extend({
    routes: {
        "tab/:tabname": "goToTab",
        "*default": "defaultTab"
    },

    goToTab: function(tabName) {
        view.renderTab(tabName);
    },

    defaultTab: function() {
        view.renderTab('markets');
    }
});
tabsRouter = new TabsRouter();

The above code works fine and i can access the routes like baseurl/#tab/personal but i want something baseurl/#personal, I don't want to start with tab. I have tried ":tabname" route but its not working.

Any help would be appreciated.

One of best way that you can solve your trouble is using different paths for each tab.

Following your code, it would be:

TabsRouter = Backbone.Router.extend({
    routes: {
        "tab/first-tab": "firstTabView",
        "tab/second-tab": "secondTabView",
        "tab/third-tab": "thirdTabView",
        "*default": "defaultTab"
    },

    firstTabView: function() {
        view.renderFirstTab();
    },
    secondTabView: function() {
        view.renderSecondTab();
    },
    thirdTabView: function() {
        view.renderThirdTab();
    },
    defaultTab: function() {
        view.renderDefault();
    }
});
tabsRouter = new TabsRouter();

Hope it helps you.
