2.html代码:
<div>
<div class="progress progress-striped active">
<div class="progress-bar" role="progressbar" aria-valuenow="" aria-valuemin="" aria-valuemax="" v-bind:style="progressStyle">进度条</div>
</div>
<button type='button' v-on:click='queryEnterprise' class='btn btn-primary'>走</button>
</div>
v-bind:style="progressStyle"
绑定内联样式:
a.对象语法:v-bind:style 的对象语法十分直观——看着非常像 CSS，其实它是一个 JavaScript 对象。CSS 属性名可以用驼峰式（camelCase）或短横分隔命名（kebab-case）：
eg:
html:
<div v-bind:style="{ color: activeColor, fontSize: fontSize + 'px' }"></div>
js:
data: {
activeColor: 'red',
fontSize:
}
直接绑定到一个样式对象通常更好，让模板更清晰：
html:
<div v-bind:style="styleObject"></div>
js:
data: {
styleObject: {
color: 'red',
fontSize: '13px'
}
}
b.数组语法: v-bind:style 的数组语法可以将多个样式对象应用到一个元素上：
eg:
html:
<div v-bind:style="[styleObjectA, styleObjectB]">
js:
data: {
styleObjectA: {
color: 'red'
},
styleObjectB:{
fontSize: '13px'
}
}
c.自动添加前缀: 当 v-bind:style 使用需要厂商前缀的 CSS 属性时，如 transform，Vue.js 会自动侦测并添加相应的前缀。
3.js代码:
<script>
export default {
components:{},
props:{},
ready:function(){},
computed:{},
methods:{
queryEnterprise:function(){
if(parseInt(this.progressStyle.width)<){
this.progressStyle.width=parseInt(this.progressStyle.width)++'%';
}else{
alert("进度条已经走完");
}
}
},
data () {
return {
//进度条样式
progressStyle:{
width:'10%',
},
}
}, }
</script>
4.style
.progress {
height: 40px;
transition: 3s;
}
.progress-bar {
font-size: 16px;
line-height: 40px;
}
