the background of the problem and what methods you have tried
<script>
function takeout(th) {
var text2 = $("textarea").val();
var allcon2 = text2.split("\n");
var str = "";
for (var i = 0; i < allcon2.length; iPP) {
str += allcon2[i].replace(/(^\s*)|(\s*$)/g, "") + "\n"
}
$(th).val(str.replace(/(^\s*)|(\s*$)/g, ""))
return true;
}
</script>now I want to remove the spaces at both ends of each column. How can I change it? there is no way of thinking or removing the spaces at both ends of each data (the spaces in the data are reserved). (the event is to point out that onblur executes takeout (this)) instructions: all spaces in value cannot be removed directly, because there may be normal spaces in the value. It is possible to have one or more delimiters except the tab key, that is, delete all the delimiters that come with the data and do not delete them. Do you have any good methods to put them back into the original textarea after removal? it is best to use jquery ~ ~ Thank you
