微信小程序Page中data数据获取和设置

一、Page中data数据的获取和设置:

       1、设置data数据 this.setData(object)

setData() 参数格式:接受一个对象,以 key,value 的形式表示将 this.data 中的 key 对应的值改变成 value。其中 key 可以非常灵活,以数据 路径的形式给出,如 array[2].message,a.b.c.d,并且不需要在 this.data 中预先定义。 

this.setData({ 
; encryptionPage: 'display:block', 
});
Copy after login

2、获取data数据 this.data.object

var text=this.data.text
Copy after login
Page({ 
 data: { 
 encryption: "color: green; border-bottom-color: green; border-bottom-size: 1px; border-bottom-style: solid;", 
 decryption: "color: gray; border-bottom-color: #F5F5F5; border-bottom-size: 1px; border-bottom-style: solid;", 
 encryptionPage:'display:block', 
 decryptionPage:'display:none', 
 originalText:'', 
 encryptedText:'', 
 originalTextDecode:'', 
 encryptedTextDecode:'', 
 encryptedPassword:'', 
 decryptedPassword:'', 
},
Copy after login
 setEncryption: function(e){ 
 this.setData({ 
 encryptionPage: 'display:block', 
 decryptionPage: 'display:none', 
 encryption: "color: green; border-bottom-color: green; border-bottom-size: 1px; border-bottom-style: solid;", 
 decryption: "color: gray; border-bottom-color: #F5F5F5; border-bottom-size: 1px; border-bottom-style: solid;", 
 }) 
 }, 
)}
