富文本响应url整体设计思路

c++的实现细节

handleOpenUrl为a标签点击后的回调函数

RichText* RichText::createWithXML(const std::string& xml, const ValueMap& defaults, const OpenUrlHandler& handleOpenUrl)
{
    RichText* widget = new (std::nothrow) RichText();
    if (widget && widget->initWithXML(xml, defaults, handleOpenUrl))
    {
        widget->autorelease();
        return widget;
    }
    CC_SAFE_DELETE(widget);
    return nullptr;
}

lua层使用

注意第三个参数

    local richText = ccui.RichText:create();
    richText:initWithXML(self:testXMLString(), {}, function(url)
        ---  url来自a标签的href属性
        print("url:", url)
        local app = cc.Application:getInstance()
        app:openURL(url)
    end);

封装1：没有地方在使用

function _M.createRichTextToTarget(parent, label, str, param)
    -- ...注意param的func属性
    if param.func then
        richText:initWithXML(str, defaults, func)
    else
        richText:initWithXML(str, defaults)
    end
    -- ...
end

封装2：大量使用

function _M.addRichText(label, str, func, ignore, isSystemFont, param)
    -- 注意第三个func参数
    if func then
        richText:initWithXML(str, defaults, func)
    else
        richText:initWithXML(str, defaults)
    end
end

• 使用1

-- X %s, Y %s
-- X 100, Y 200
richText = Common.addRichText(node.info.TextContent, text, handler(self, self.onClickSharePos), nil)
function _M:onClickSharePos(str)
    local data = str.split(str, ",")
    if #data == 2 then
        self:close()
        SocketMgr:sendInnerMsg(InnerProtocol.innerMove2CamPve, {gridId = MapUtil:getGridIdByPos(tonumber(data[1]), tonumber(data[2])), time=0.2})
    end
end

• 使用2

txt = string.format("%s", txt) --下划线 href写死了
local lineClickEvent = function()
end
Common.addRichText(self._csbControl.renwu_shu.texttask, txt, function()
            lineClickEvent()
        end, false)

封装3：没有地方在使用

function _M.createRichText(str, func)
    local richText = ccui.RichText:create()
    richText:initWithXML(str, {}, func)
    return richText
end

protocol协议

href的完整格式

protocol://host/path

protocol	host	path	search
file
ftp
http
https
ws
wss
app
game	bag	show-item	id="001"

• case:游戏里面打开背包，并展示ID为001的物品
