Question

我更改了以下对象ID的ID ..我试图在点击时更改视频：

<object id="aeroVideo" class="BrightcoveExperience">
  <param name="bgcolor" value="#FFFFFF" />
  <param name="width" value="480" />
  <param name="height" value="270" />
  <param name="isVid" value="true" />
  <param name="isUI" value="true" />
  <param name="dynamicStreaming" value="true" />
  <param name="wmode" value="transparent" />  
</object>

<div id="pic2"> 
  <div id="pic2a"></div> 
  <div id="pic2b"></div>   
</div> <!-- end of pic2 -->

<script type="text/javascript">
$( document ).ready(function() {   

var aeroVideo = $("#aeroVideo");

$('#pic2a').click(function(){
console.log("inside pic2a");

if (aeroVideo.length == 0){
aeroVideo = "myExperience3427230656001";
console.log("inside pic2a without variable set");
}
else if (aeroVideo.length != 0){
aeroVideo = "myExperience3427230656001";
console.log("inside pic2a with variable set");
}

});

$('#pic2b').click(function(){
console.log("inside pic2b");

if (aeroVideo.length == 0){
aeroVideo = "myExperience3427216723001";
console.log("inside pic2b without variable set");
}
else if (aeroVideo.length != 0){
aeroVideo = "myExperience3427216723001";
console.log("inside pic2b with variable set");
}

});

});


</script>

跑步时的控制台告诉我我在pic2a或pic2b里面有变量设置（从不没有变量设置）但是它根本没有像插入视频的字符串那样改变视频名称...

Answer 1

您将aeroVideo设置为字符串值，而不是更改ID。

您想要更改此内容：aeroVideo = 'myExperience3427230656001';

对此：aeroVideo.attr('id', 'myExperience3427230656001');。

此外，如果aeroVideo为空（{jQuery没有找到它），aeroVideo.length == 0会返回true，所以您可能只想要aeroVideo.length。

Answer 2

即兴表达问题。看起来代码尝试将字符串设置为aeroVideo。至少它必须使用DOM对象的属性

将jquery字符串插入对象id：
