This tutorial teaches you how to make a "walking" bootstrap progress bar for your reference. The specific content is as follows
1. Page effect:
Starting position:
After clicking the "Go" button
2 .html code:
<div> <div class="progress progress-striped active"> <div class="progress-bar" role="progressbar" aria-valuenow="45" aria-valuemin="0" aria-valuemax="100" v-bind:style="progressStyle">進(jìn)度條</div> </div> <button type='button' v-on:click='queryEnterprise' class='btn btn-primary'>走</button> </div>
v-bind:style="progressStyle"
Bind inline style:
a. Object syntax: The object syntax of v-bind:style is very intuitive - it looks very like CSS, Actually it is a JavaScript object. CSS property names can be named in camelCase or kebab-case:
eg:
html:
<div v-bind:style="{ color: activeColor, fontSize: fontSize + 'px' }"></div>
js:
data: {
activeColor: 'red',
fontSize: 30
}
directly bound to a Style objects are usually better and make the template clearer:
html:
<div v-bind:style="styleObject"></div>
js:
data: {
styleObject: {
color: 'red',
fontSize: '13px'
}
}
b. Array syntax: The array syntax of v-bind:style can combine multiple style objects Applied to an element:
eg:
html:
<div v-bind:style="[styleObjectA, styleObjectB]">
data: {
styleObjectA: {
color: 'red'
},
styleObjectB:{
fontSize: '13px'
}
}
c. Automatically add prefix: When v-bind:style uses CSS properties that require vendor prefixes, such as transform, Vue.js will automatically Detect and add the appropriate prefix.
3.js code:
<script>
export default {
components:{},
props:{},
ready:function(){},
computed:{},
methods:{
queryEnterprise:function(){
if(parseInt(this.progressStyle.width)<100){
this.progressStyle.width=parseInt(this.progressStyle.width)+30+'%';
}else{
alert("進(jìn)度條已經(jīng)走完");
}
}
},
data () {
return {
//進(jìn)度條樣式
progressStyle:{
width:'10%',
},
}
},
}
</script>
4.style
.progress {
height: 40px;
transition: 3s;
}
.progress-bar {
font-size: 16px;
line-height: 40px;
}
