Uncaught SyntaxError: Unexpected identifier
提问by Dvir Levy
hello im am getting JS error :
你好，我收到 JS 错误：
Uncaught SyntaxError: Unexpected identifier
here
这里
<script type="text/javascript">
var cur_level = 1;
var ids_arr = new Array(<?php echo $max_level?>);
var im_here = new Array(<?php echo $max_level?>);
ids_arr[0] = 1;
im_here[0] = "|";
function displayData(id, level, used, title)
{
if(used){
choice = document.getElementById('divv'+id).innerHTML;
document.getElementById('test_div').innerHTML = choice;
} else {
document.getElementById('test_div').innerHTML = ' No lerning paths to show.';
updateLinksDiv(id, level, title);
}
}
function updateLinksDiv(id, level, title)
{
var links_div_info = document.getElementById('links_parent_'+id);
var tmpHTML = '';
var here = '';
for(i=0;i<level;i++){
here+= '->'+im_here[i];
links_div_info = document.getElementById('links_parent_'+ids_arr[i]);
tmpHTML += '<div id="divl_'+links_div_info.id+'">'+links_div_info.innerHTML+'</div>';
}
links_div_info = document.getElementById('links_parent_'+id);
tmpHTML += '<div id="divl_'+links_div_info.id+'">'+links_div_info.innerHTML+'</div>';
document.getElementById('links').innerHTML = tmpHTML;
ids_arr[i] = id;
im_here[i] = title;
}
</script>
<script type="text/javascript">
window.onload=updateLinksDiv(1 , 0 , "|" ) ;
</script>
the functions are suppose to create an "expanding" that opens up with levels and everything was working fine untill i added the "title" and i started getting the error. the error points me to the last and i just cant find the error... i try to call displayData like this
这些函数应该创建一个“扩展”，它会随着级别打开并且一切正常，直到我添加了“标题”并且我开始收到错误消息。错误将我指向最后一个，我只是找不到错误...我尝试像这样调用 displayData
onclick="displayData('.$cat->id.','.$cat->level.',0,'.$cat->title.')"
any suggestions for what i'm not seeing.?
对于我没有看到的任何建议。？
thank you
谢谢

In your comment you say that displayData(26,1,0,???? ?)is generated. This explains the symptoms, as here the last parameter contains a space in addition to Hebrew letters, so the JavaScript intepreter sees it as two identifiers separated by a space, and the identifiers are probably undefined. Google Chrome gives the error message you describe, whereas Firefox and IE say, more enigmatically, “missing ) after argument list.”
在您的评论中，您说这displayData(26,1,0,???? ?)是生成的。这解释了症状，因为这里的最后一个参数除了希伯来字母之外还包含一个空格，因此 JavaScript 解释器将其视为由空格分隔的两个标识符，并且标识符可能未定义。谷歌浏览器给出了你描述的错误信息，而 Firefox 和 IE 更神秘地说，在参数列表之后“缺少 )”。
Apparently the generated code is supposed to have the last parameter in quotation marks, i.e. '???? ?'. You need to modify the generation to contain them.
显然，生成的代码应该在引号中包含最后一个参数，即 '???? ？'。您需要修改生成以包含它们。
