var select = 'dd[lay-value=' + blog.UserId + ']';
$('#advertisementUserId').siblings("div.layui-form-select").find('dl').find(select).click();另外记录上次选中，我选择用 sessionStorage，demo
<script>
// 检测浏览器支持
if (typeof(Storage) !== "undefined") {
// 存储
sessionStorage.setItem("lastname", "Smith");
// 检索
document.getElementById("result").innerHTML = sessionStorage.getItem("lastname");
} else { document.getElementById("result").innerHTML = "Sorry, your browser does not support Web Storage...";
}
</script>但是若 value 中含特殊字符等会导致查询报错，只需在 lay-value= 后加双引号即可
var select = 'dd[lay-value="' + pointOption + '"]';
