Hello

Could anyone say to me if it's possible to create a javascript code which reads a text file and fill an array with the lines contained in it?


Thanks in advance

Check the code snippet below, the html/javascript code reads 2 files from the C: drive. If you are working on Unix or Linux, change the path of the file accordingly.

Hope this helps
<html>
 
<head>
  <title></title>
</head>
 
<body>
<script language="JavaScript" type="text/javascript">
<!--
var srcFrame;
//External content into a layer
function loadOuter(doc) {
 srcFrame = document.getElementById("hiddenContent");
 srcFrame.src = doc;
 // workaround for missing onLoad event in IFRAME for NN6
 if (!srcFrame.onload) {
  setTimeout("transferHTML()", 1000)
 }
}
 
function transferHTML(){
 srcContent='';
 if (srcFrame.contentDocument){
  srcContent=srcFrame.contentDocument.getElementsByTagName("BODY")[0].innerHTML;
 }
 else if (srcFrame.contentWindow){
  srcContent=srcFrame.contentWindow.document.body.innerHTML;
 }
 document.getElementById("outerDisplay").innerHTML = srcContent
}
 
 
var DocAry=new Array('text1.txt','text2.txt');
 
function SelectList(v){
 if (v>0){
  loadOuter(DocAry[v-1]);
 }
}
 
//-->
</script>
 
<INPUT TYPE="button" VALUE="text1.txt" onClick="loadOuter('C:\\text1.txt')" >
<INPUT TYPE="button" VALUE="text2.txt" onClick="loadOuter('C:\\text2.txt')" >
<br>
 
<div id="outerDisplay"></div>
 
<iframe  id="hiddenContent" width="200" height="200" style="position:absolute;visibility:hidden;" ></iframe>
 
</body>
 
</html>

Open in new window

text1.txt
text2.txt
