今天做登录页面时要做一个验证滑块的功能。
因为不想去写样式引用了组件。在网上找了很久，个人认为可以的一款组件
{{ confirmWords }}
ref="moveDiv"
@mousedown="mouseDownFn($event)"
:class="{ handler_ok_bg: confirmSuccess }"
class="handler handler_bg"
style="position: absolute; top: 0px; left: 0px;"
>
export default {
data() {
return {
beginClientX: 0 /*距离屏幕左端距离*/,
mouseMoveState: false /*触发拖动状态 判断*/,
maxWidth: "" /*拖动最大宽度，依据滑块宽度算出来的*/,
confirmWords: "请按住滑块，拖动到最右边" /*滑块文字*/,
confirmSuccess: false /*验证成功判断*/
};
},
methods: {
//mousedown 事件
mouseDownFn: function(e) {
if (!this.confirmSuccess) {
e.preventDefault && e.preventDefault(); //阻止文字选中等 浏览器默认事件
this.mouseMoveState = true;
this.beginClientX = e.clientX;
}
},
//验证成功函数
successFunction() {
this.$store.commit("statestatus", true);
this.confirmSuccess = true;
this.confirmWords = "验证通过";

样式如下：
![]()
![]()
因为要做一个验证通过后马上显示验证码的输入框。要做一个判断。但是发现出发的事件要在组件内才行。
这里我用了vuex，存储一个状态。然后在组件中获取，并返回vuex中state一个状态。
this.$store.commit("statestatus", true);
