寫了個簡單的彈窗插件Prompt.js, 效果圖如下

功能: 仿iOS彈出效果, 背景模糊, 可傳入的確定和取消回調(diào)函數(shù)等.

不帶參數(shù)調(diào)用:

Prompt()

會按照默認(rèn)參數(shù)和回調(diào)函數(shù)調(diào)用

帶參數(shù)調(diào)用:

目前有四個參數(shù) - 標(biāo)題(str), 內(nèi)容(str), 確定回調(diào)(function), 取消回調(diào)(function). 其中取消回調(diào)和標(biāo)題是可選的, 而內(nèi)容和確定回調(diào)必填.

javascript
Prompt({content: "確定取消關(guān)注達(dá)人?", okCallback:function(){void(0)}, cancelCallback:function(){void(0)}})

按參數(shù)自動重載

當(dāng)沒有傳入取消回調(diào)函數(shù)時, 只會顯示"確定"按鈕.
