我有一个div,里面有很多跨距。现在,我想读取所有span的所有文本以及thirr-id,并将其填充到一个javascript映射中,其中key=spanid和value=“text of span。我该怎么做?”?
Eg <div mydiv="xyx" >
<span id ="sp1" > M/span>
<span id ="sp2" > M/span>
....
..
</div>
如何填充地图?

您可以使用document.getElementById
和document.getElementsByTagName
获取元素,然后遍历它们并将它们添加到对象中。使用textContent
和innerText
以获取span
元素的文本,并将它们插入对象中,如下所示:
var spans = document.getElementById( xyx ).getElementsByTagName( span ),
obj = {};
for(var i = 0, l = spans.length; i < l; i++){
obj[spans[i].id] = spans[i].textContent || spans[i].innerText;
}
var container=document.getElementById( xyx );
var spanArray=container.getElementsByTagName( span );
for(var s=0;s<spanArray.length;s++){
spanText=spanArray[s].innerHTML;
}
使用Jquery非常简单:
var spans = $( #xyx ).find( span );
var arr = new Array();
foreach(spans as span)
{
arr[$(span).attr( id )] = $(span).text;
}
希望我能帮上忙。
Update: None jquery way:
var spans = document.getElementById( xyx );
spans = spans.getElementsByTagName( span );
var arr = new Array();
foreach(spans as span)
{
arr[span.getAttribute( id )] = arr[span.innerHTML];
}
