Vue中在调用后台接口的回调方法中将返回值绑定到字符串中。

并且在字符串中可以结合三目表达式判定，如果返回值的某个属性为空则显示空字符串。

注：

实现

1、使用方式

:title="`字符串${xx}`"

2、使用示例

                            getCarContent(param).then((res) => {
                                content = res.data;
                                    str =`
                                        <div class="car_detail">
                                            <div class="car_detail_header">
                                                <p>驾驶员：${content.drivername? content.drivername: ""}</p>
                                                <p>号码：<span id="car_isOnline_sip">${content.sipNumber ? content.sipNumber : ""}</span></p>
                                                <p style="overflow: hidden;text-overflow: ellipsis;white-space: nowrap;-webkit-line-clamp: 3;" title="${content.site}">
                                                    位置：${content.site? content.site: ""}
                                                </p>
