本篇主要说明表单控件的数据绑定，这次没有新的知识点
文本框
1、普通文本框
<div id="app-1">
<p><input v-model="textBox" placeholder="输入内容...">输入的内容：{{ textBox }}</p>
</div>
<script type="text/javascript">
var vm1 = new Vue({
el: '#app-1',
data: {
textBox: ''
}
})
</script>
2、数字文本框
<div id="app-1">
<p><input v-model.number="numberTextBox" type="number" placeholder="输入内容..."> 输入的内容：{{ numberTextBox }}</p>
</div>
<script type="text/javascript">
var vm1 = new Vue({
el: '#app-1',
data: {
numberTextBox: ''
}
})
</script>
.number参数会强制把返回值转成Number类型，因为就算是type="number"，返回的也是字符串型
3、多行输入框
<div id="app-1">
<p><textarea v-model="multiTextBox" placeholder="输入内容..."></textarea></p>
<p>输入的内容：</p>
<p style="white-space:pre">{{ multiTextBox }}</p>
</div>
<script type="text/javascript">
var vm1 = new Vue({
el: '#app-1',
data: {
multiTextBox: ''
}
})
</script>
style="white-space:pre"表示空白会被浏览器保留。其行为方式类似 HTML 中的 <pre> 标签
复选框
1、单个复选框
<div id="app-1">
<input type="checkbox" id="checkbox" v-model="singleCheckBox">
<label for="checkbox">{{ singleCheckBox }}</label>
</div>
<script type="text/javascript">
var vm1 = new Vue({
el: '#app-1',
data: {
singleCheckBox: false
}
})
</script>
</body>
2、定义属性单个复选框
<div id="app-1">
<input type="checkbox" id="checkbox" v-model="customSingleCheckBox" v-bind:true-value="customTrue" v-bind:false-value="customFalse">
<label for="checkbox">{{ customSingleCheckBox }}</label>
</div>
<script type="text/javascript">
var vm1 = new Vue({
el: '#app-1',
data: {
customTrue: '真',
customFalse: '假',
customSingleCheckBox: '假'
}
})
</script>
v-bind:true-value设置为真时的属性，v-bind:false-value设置为假时的属性
3、多个复选框
<div id="app-1">
<input type="checkbox" id="tansea" value="TanSea" v-model="multiCheckBox">
<label for="tansea">TanSea</label>
<input type="checkbox" id="google" value="Google" v-model="multiCheckBox">
<label for="google">Google</label>
<input type="checkbox" id="baidu" value="Baidu" v-model="multiCheckBox">
<label for="baidu">Baidu</label>
<p>选择的项：{{ multiCheckBox }}</p>
</div>
<script type="text/javascript">
var vm1 = new Vue({
el: '#app-1',
data: {
multiCheckBox: []
}
})
</script>
单选框
<div id="app-1">
<input type="radio" id="male" value="男" v-model="radioBox">
<label for="male">男</label>
<input type="radio" id="female" value="女" v-model="radioBox">
<label for="female">女</label>
<p>选择的项：{{ radioBox }}</p>
</div>
<script type="text/javascript">
var vm1 = new Vue({
el: '#app-1',
data: {
radioBox: ''
}
})
</script>
下拉框
1、普通下拉框
<div id="app-1">
<select v-model="comboBox">
<option disabled value="">请选择一项</option>
<option>男</option>
<option>女</option>
</select>
<p>选择的项：{{ comboBox }}</p>
</div>
<script type="text/javascript">
var vm1 = new Vue({
el: '#app-1',
data: {
comboBox: ''
}
})
</script>
2、动态绑定下拉框
<div id="app-1">
<select v-model="dynamicComboBox">
<option v-for="optionItem in optionItems" v-bind:value="optionItem.value">
{{ optionItem.text }}
</option>
</select>
<p>选择的项：{{ dynamicComboBox }}</p>
</div>
<script type="text/javascript">
var vm1 = new Vue({
el: '#app-1',
data: {
dynamicComboBox: '',
optionItems: [
{ value: 'TanSea', text: '双子宫殿' },
{ value: 'Google', text: '谷歌搜索' },
{ value: 'Baidu', text: '百度搜索' }
]
}
})
</script>
3、多选列表
<div id="app-1">
<p><select v-model="multiComboBox" multiple>
<option>双子宫殿</option>
<option>谷歌搜索</option>
<option>百度搜索</option>
</select></p>
<p>选择的项：{{ multiComboBox }}</p>
</div>
<script type="text/javascript">
var vm1 = new Vue({
el: '#app-1',
data: {
multiComboBox: []
}
})
</script>
