使用场景：
<view class="info_input"><input type="{{passwordType}}" placeholder-class="incolor" maxlength="16" name="password" placeholder="请输入密码" /><view catchtap="testTap" class="look_pwd incursor"></view></view>
var indexPwdType = 'password';
var pageObject = {
data: {
passwordType: indexPwdType,
},
...
}
testTap: function () {
if (indexPwdType == 'password') {
indexPwdType = 'text';
this.setData({
passwordType: 'text'
});
} else {
indexPwdType = 'password';
this.setData({
passwordType: 'password'
});
}
}
如果眼睛需要变换背景图片，那么
testTap: function () {if (indexPwdType == 'password') {indexPwdType = 'text';var show = "http://cache.img.etailor.me/wap/appimg/xcx/new_img/show2.png";this.setData({passwordType: 'text',BackgroundImg: show});} else {indexPwdType = 'password';var noshow = "http://cache.img.etailor.me/wap/appimg/xcx/new_img/no_show.png";this.setData({passwordType: 'password',BackgroundImg: noshow});}}
在data里双向绑定一个数据
BackgroundImg:"http://cache.img.etailor.me/wap/appimg/xcx/new_img/show2.png"
<view catchtap="testTap" class="look_pwd incursor" style="background-image: url({{BackgroundImg}})"></view>
