vue手动实现多选框

Posted 2021-09-06 嘴巴嘟嘟

点击按钮选中，再点击其他按钮也都选中的业务需求

 <p class="one-button"   @click="commentFetch2(2,'pr2','productStatus','pr1','pr2','pr3','pr4','ProductStatus2')"></p>

首先注意的是这个数组只能接受四个数字，1，2，3，4. 所以我们首先对数据去重，然后取消点击的时候删除此时的数据，

 let commentFetch2 = (key, value, type, val1, val2, val3, val4, istype) => {
                state.params[type].push(key);
                state.params[type] = [...new Set(state.params[type])];
                if (value == val1) {
                    state[istype] = !state[istype];
                    if (state[istype] === true) {
                        state.assetLists = [];
                        fetchData();
                    } else {
                        state.params[type].splice(state.params[type].findIndex(item => item === key), 1);
                        fetchData();
                    }

                }
                if (value == val2) {
                    state[istype] = !state[istype];
                    if (state[istype] === true) {
                        state.assetLists = [];
                        fetchData();
                    } else {
                        state.params[type].splice(state.params[type].findIndex(item => item === key), 1);
                        fetchData();
                    }
                }
                if (value == val3) {
                    state[istype] = !state[istype];
                    if (state[istype] === true) {
                        state.assetLists = [];
                        fetchData();
                    } else {
                        state.params[type].splice(state.params[type].findIndex(item => item === key), 1);
                        fetchData();
                    }
                }
                if (value == val4) {
                    state[istype] = !state[istype];
                    if (state[istype] === true) {
                        state.assetLists = [];
                        fetchData();
                    } else {
                        state.params[type].splice(state.params[type].findIndex(item => item === key), 1);
                        fetchData();
                    }
                }
            };
