使用<代码>get() 是只能读到txt文档的第一行吗?

例如:

jQuery.get( file.txt , function(data) {
   alert(data);
   //process text file line by line
   $( #div ).html(data.replace( 
 , <br> ));
});

但仅读到第一行?

任何其他建议?

最佳回答

这可能比使用<代码>split的版本要快一些,因为它赢得了整个<代码>>>><数据/代码>的拼凑,而只是搜索第一新线。

data.substr(0, data.indexOf("
"));
问题回答

Split the contents of the file into lines, then retrieve the first element.

alert(data.split( 
 )[0]);

曾进行过检测,但应当奏效。
