I have large string with repeated some small string in JavaScript. I want to remove only that particular string but symbols should not remove or changed.
The large string is -
var temp="day=1-CT=18-box=calender1_day=2-CT=19-CT=20-box=calender2_day=3-CT=30-box=calender3";
IN above string three sub string is joined with underscore(_). so I want to remove 'box=calender(n)' from each from these three sub string. Please help. Thanks in Advanced.
Use simple string replacement function. Wherever box=calender(n) is found, it will be deleted.
temp = temp.replace('box=calender(n)','');
Try like this :
<script>
function myFunction()
{
var temp="day=1-CT=18-box=calender1_day=2-CT=19-box=calender2_day=2-CT=20-box=calender2_day=3-CT=30-box=calender3";
str = temp.replace(/box=calender\d/g, '');
alert(str);
}
myFunction();
</script>
may be here is your clue for your search
$temp="day=1-CT=18-box=calender1_day=2-CT=19-CT=20-box=calender2_day=3-CT=30-box=calender3"; $patterns = array ('/box=calender[0-9]/',); $replace = array (''); echo preg_replace($patterns, $replace, $temp);
output
day=1-CT=18-_day=2-CT=19-CT=20-_day=3-CT=30-
Try:
var temp="day=1-CT=18-box=calender1_day=2-CT=19-box=calender2_day=2-CT=20-box=calender2_day=3-CT=30-box=calender3";
temp = temp.replace(/box=calender./g,"");
Can you try this,
var temp="day=1-CT=18-box=calender1_day=2-CT=19-box=calender2_day=2-CT=20-box=calender2_day=3-CT=30-box=calender3";
var pt = /box=calender\d/g;
temp = temp.replace(pt, "");
