In input field need to replace , with ..

With HTM such code is working onkeyup="this.value = this.value.replace(/,/g,'.')"

But need to use in php (with echo) like this:

echo '<input type="text" name="amount_1" onkeyup="this.value = this.value.replace(/,/g,'.')" style="width:53px;"></input>';

With php does not work. If use this this.value.replace(/,/g,/./) then , is replaced with /./.

Tried (/,/g,"/./"), (/,/g,/"."/), (/,/g,.) nothing works (I mean , does not change to .).

Any ideas?

• php
• javascript

• What you mean about "does not work"? Errors or something? – Ionică Bizău Commented Jun 23, 2013 at 6:47

You have to escape the ' with a backslash in your PHP code.

echo '<input type="text" name="amount_1" onkeyup="this.value = this.value.replace(/,/g,\'.\')" style="width:53px;"></input>';

Otherwise you are cuting your string into to pices an put it together with the point.
