Question

x = d3.scaleBand().rangeRound([0, width]).paddingInner(0.1);
xAxis = d3.axisBottom(this.x).ticks(10);

x.domain(dummyData.map( d => d.name ));

    svg
    .append('g')
        .attr('class', 'x axis')
        .attr('transform', `translate( 0 , ${height})`)
        .call(xAxis)
    .selectAll('.tick')
    .append('foreignObject')
    .append('xhtml:div'))
        .style('background-image', d => `url(${d.imgUrl})`)
        .style('background-size','30px')
        .style('background-repeat', 'no-repeat')

我想输出类似

var item = $(documentListItem + "[index=" + documentListSelectedIndex + "]");
item[0].scrollIntoView({ behavior: "instant", block: "center", inline: "nearest" });

使用UNION，例如：

SELECT id,name,add1 from mytable
UNION
SELECT id,name,add2 from mytable

编辑：为了获得更好的性能，您可以改用UNION ALL，这将为您提供相同的结果：

SELECT id,name,add1 from mytable
 UNION ALL
SELECT   id,name,add2 from mytable
