javascript

Javascript validates that the type of uploaded file must be limited to certain formats


//Verify the format of the file
function validateFile(){
var fileObject=$("#filename");
var errorObject=$("#error");
var filepath=fileObject.val();
var fileArr=filepath.split("//");
var fileTArr=fileArr[fileArr.length-1].toLowerCase().split(".");
var filetype=fileTArr[fileTArr.length-1];
if(filetype!="xls"&&filetype!="xlsx"&&filetype!="doc"&&filetype!="docx"
&&filetype!="jpeg"&&filetype!="jpg"&&filetype!="ppt"&&filetype!="pptx"
&&filetype!="txt"&&filetype!="bmp"&&filetype!="png"&&filetype!="gif"){
fileObject.focus();
errorObject.html(" Upload files must be pictures, doc , ppt , xls , txt File! ");
}else{
errorObject.remove();
}
}
