我想知道如何动态获取数组索引值。
在这里,我正在自定义编码中使用的 quizy-fillintheblanks.master.zip 文件:
<script>
$('#tutorial-fillblank').quizyFillBlank({
textItems:['The first president of the United States of America is', '. The longest serving president of the country is ', '. He was succeeded by ', ', who led the country till the end of the Second World War. The first afro-american to be elected for this position is', '.'],
anItems:['John Kennedy', 'Franklin Roosevelt', 'George Washington', 'Ronald Reagan', 'Harry Truman', 'Richard Nixon', 'Barack Obama' ],
anItemsCorrect:[2,1,4,6],
blockSize:150
});
</script>
在上面的编码中,textItems 是问题,anItems 是答案,anItemCorrect 是 anItems 的数组索引值。
在该编码中,我将从数据库中获取的值自定义为问题和答案。这里我不知道如何动态传递 anItemCorrect 值:
<script>
$('#tutorial-fillblank').quizyFillBlank({
textItems:[<?php foreach($question as $article) { echo "'".$article->question."',";}?>],
anItems:[<?php foreach($question as $article)
{$a[]=$article->answer;}
$arr=$a; shuffle($arr); foreach($arr as $ans => $val) {echo "'".$val."',";} ?> ],
anItemsCorrect:[<?php foreach($arr as $ans => $val) { echo "'".$ans."',";} ?>],
blockSize:150
});
</script>
如何使用 jquery.inArray() 动态选择答案是对还是错?
