本文實(shí)例講述了jQuery實(shí)現(xiàn)帶漸顯效果的人物多級(jí)關(guān)系圖。分享給大家供大家參考。具體如下：
這里演示jQuery實(shí)現(xiàn)帶漸顯效果的人物多級(jí)關(guān)系圖，setQuestPose:function中的n代表共幾個(gè)對(duì)象 r代表周長(zhǎng) i代表第幾個(gè)對(duì)象 w代表外面對(duì)象的寬帶 h代表外面對(duì)象的高度 d代表其實(shí)角度，測(cè)試時(shí)請(qǐng)注意，如果右下角提示有錯(cuò)誤，請(qǐng)重新刷新頁(yè)面即可。
運(yùn)行效果截圖如下：
