vue 参数拼接没有值问题? 如下提交方法: handleHighSubmit(data) { this.serverData = { ...data } const new_str = [this.form.server_str, this.serverData.highServer].join(',') let params = { choice: this.choice, filter_condition: { server_str: new_str, ...this.form } } console.log(params, 'params---'); this.getCoverUsers(params) this.handleClose() }, 我在控制台打印的this.form.server_str值为字符串`'123'`和this.serverData.highServer的值为`‘[2-3]’`,它们都有值,,然后通过join拼接到一块当做参数传递,拼接后的值是'123,[2-3]',但是提交到接口为什么就只有this.form.server_str值,没有this.serverData.highServer的值
