官方文档中说 可以 对确认弹窗做一些显示设置。如文字 颜色

https://uniapp.dcloud.io/api/ui/prompt?id=showmodal

但是经过测试 APP不支持修改颜色 附带通用弹窗函数 写在相应的模块方法中

confirm(content, callBack, params) {
    if (params == undefined) {
        params = {}
    }
    if (params.title == undefined) {
        params.title = '友情提醒';
    }
    if (params.showCancel == undefined) {
        params.showCancel = true;
    }
    if (params.confirmText == undefined) {
        params.confirmText = '确定';
    }
    if (params.confirmColor == undefined) {
        params.confirmColor = '#007aff';
    }
    if (params.cancelText == undefined) {
        params.cancelText = '取消';
    }
    if (params.cancelColor == undefined) {
        params.cancelColor = '#000000';
    }
    //APP 没法该按钮颜色
    uni.showModal({
        title: params.title,
        content: content,
        success: callBack,
        showCancel: params.showCancel,
        confirmText: params.confirmText,
        confirmColor: params.confirmColor,
        cancelText: params.cancelText,
        cancelColor: params.cancelColor
    });
}
