以下將展示微信小程序之表單組件input源碼官方組件能力,，組件樣式僅供參考,，開發(fā)者可根據(jù)自身需求定義組件樣式，具體屬性參數(shù)詳見小程序開發(fā)文檔,。 功能描述： 輸入框,。該組件是原生組件，使用時(shí)請注意相關(guān)限制 屬性說明： WebView：
Skyline：
Bug & Tip 1.tip: confirm-type的最終表現(xiàn)與手機(jī)輸入法本身的實(shí)現(xiàn)有關(guān),，部分安卓系統(tǒng)輸入法和第三方輸入法可能不支持或不完全支持 2.tip : input 組件是一個(gè)原生組件,，字體是系統(tǒng)字體，所以無法設(shè)置 font-family 3.tip : 在 input聚焦期間,，避免使用 css 動(dòng)畫 4.tip : 對于將input 封裝在自定義組件中,、而 form 在自定義組件外的情況， form 將不能獲得這個(gè)自定義組件中 input 的值,。此時(shí)需要使用自定義組件的 內(nèi)置 behaviors wx://form-field 5.tip : 鍵盤高度發(fā)生變化,，keyboardheightchange事件可能會(huì)多次觸發(fā)，開發(fā)者對于相同的height 值應(yīng)該忽略掉 6.bug : 微信版本6.3.30, focus 屬性設(shè)置無效 7.bug : 微信版本6.3.30, placeholder 在聚焦時(shí)出現(xiàn)重影問題 示例代碼： JAVASCRIPT： Page({
data: {
focus: false,
inputValue: ''
},
bindKeyInput: function (e) {
this.setData({
inputValue: e.detail.value
})
},
bindReplaceInput: function (e) {
var value = e.detail.value
var pos = e.detail.cursor
var left
if (pos !== -1) {
// 光標(biāo)在中間
left = e.detail.value.slice(0, pos)
// 計(jì)算光標(biāo)的位置
pos = left.replace(/11/g, '2').length
}
// 直接返回對象,，可以對輸入進(jìn)行過濾處理,，同時(shí)可以控制光標(biāo)的位置
return {
value: value.replace(/11/g, '2'),
cursor: pos
}
// 或者直接返回字符串,光標(biāo)在最后邊
// return value.replace(/11/g,'2'),
},
bindHideKeyboard: function (e) {
if (e.detail.value === '123') {
// 收起鍵盤
wx.hideKeyboard()
}
}
