php javascript onclick value change

Question

I want to remove the "http" if it is put in the url part of the input link, before the data is sent.

this my input code look onclick=

<input style="    outline: none;" type="button" onclick="formatText ('link:url');" class="btn btn-yeni" value="link"/>

This my javascript code (the received data is sent to another file and replaced.)

<script type="text/javascript">
function formatText(tag) {
   var Field = document.getElementById('entry_girdi');
   var val = Field.value;
   var selected_txt = val.substring(Field.selectionStart, Field.selectionEnd);
   var before_txt = val.substring(0, Field.selectionStart);
   var after_txt = val.substring(Field.selectionEnd, val.length);
	Field.value += '(' + tag + ')';
}
</script>

what i want to do If the input value is "link: http: //example.com" I would like to change it and post it as "link: example.com".

Can you try in your url string :

var result = url.replace(/(\w+:|^)\/\//, '');

result variable will hold "link : example.com" in place of "link : http://example.com"

Onclick does not work when I write this between the codes. the operation of the system is as follows; OnClick is sending data to the textarea field. then this data is posted with submit. I want to remove the http tag in onclick before posting. thanks, but the code you gave did not work.

is document.getElementById('entry_girdi') the element that hold the url value ?

yes but onclick does not work when I write your code between JavaScript codes at the top.

if you replace var val = Field.value; line with this line var val = Field.value.replace(/(\w+:|^)\/\//, '') what happens ? <br> and you'll need only this part if you want only to remove the "http://" string from url then you can return it as return val + '(' + tag + ')'

for url i mean the Field.value which hold the url that you want to format. sorry for not being clear :). also this regex will help you even if the url has "https://" ;)

Use the replace() function to replace part of a string.

function formatText(tag) {
  var Field = document.getElementById('entry_girdi');
  Field.value = Field.value.replace("http://", "");
  Field.value += '(' + tag + ')';
}

Why did you delete the lines I selected? I am sending data to another file using these lines.

var selected_txt = val.substring(Field.selectionStart, Field.selectionEnd);    var before_txt = val.substring(0, Field.selectionStart);    var after_txt = val.substring(Field.selectionEnd, val.length);

The code never used any of those variables, and they didn't seem relevant to the question. You can add them back in your complete application.
