为什么这段先查询后取单元格值的代码无法得到单元格值?只有分开两段代码(先查询、后取单元格值)后才可以呢?代码://在分页模式下_g().parameterCommit()sleep(5000);var a = $("tr","div.content-container").children().eq(1).html(); alert("第3行第2列值为:"+a); //休眠函数function sleep(numberMillis){var now = new Date(); var exitTime = now.getTime() + numberMillis; while (true) { now = new Date(); if (now.getTime() > exitTime) return;}}
