element的input,focus时,不会取消占位. 现需要focus时,取消占位
<el-input v-model="form.username" :placeholder="placeholder1" @focus="focushandle" @blur="blurhandle" prefix-icon="el-icon-search" ></el-input> focushandle(event) { event.target.placeholder = ""; }, blurhandle(event) { if (event.target.value == "") { if (event.target.type == "password") { event.target.placeholder = this.placeholder2; } else { event.target.placeholder = this.placeholder1; } } }这里只有用户名和密码,所以用event.target.type == "password" 来区分,若是其他,可通过设置id,来区分
