Class 与 Style 如何动态绑定?
- 对象语法:
<div v-bind:class="{ active: isActive, 'text-danger': hasError }"></div> data: {isActive: true,hasError: false }
- 数组语法:
<div v-bind:class="[isActive ? activeClass : '', errorClass]"></div> data: {activeClass: 'active',errorClass: 'text-danger' }
Style 也可以通过对象语法和数组语法进行动态绑定:
- 对象语法:
<div v-bind:style="{ color: activeColor, fontSize: fontSize + 'px' }"></div> data: {activeColor: 'red',fontSize: 30 }
- 数组语法:vue-router 路由模式有几种?
<div v-bind:style="[styleColor, styleSize]"></div> data: {styleColor: {color: 'red'},styleSize:{fontSize:'23px'} }
vue-router 路由模式有几种?
vue-router 有 3 种路由模式:hash、history、abstract,对应的源码如下所示:
switch (mode) {case 'history':this.history = new HTML5History(this, options.base)breakcase 'hash':this.history = new HashHistory(this, options.base, this.fallback)breakcase 'abstract':this.history = new AbstractHistory(this, options.base)breakdefault:if (process.env.NODE_ENV !== 'production') {assert(false, `invalid mode: ${mode}`)}
}
