javascript - Replace function using jquery -

-

i have code here:

 txtname.value = txtname.value.replace(/(\r?\n){2,}/, '\n').replace(/^\r?\n|\r?\n$/, ''); txturl.value = txturl.value.replace(/(\r?\n){2,}/, '\n').replace(/^\r?\n|\r?\n$/, ''); txtusage.value = txtusage.value.replace(/(\r?\n){2,}/, '\n').replace(/^\r?\n|\r?\n$/, '');

how put in jquery? i've tried many things , doesn't work.

    txtname = $('#emotename');     txturl = $('#emoteurl');     txtusage = $('#emoteusage'); 

var $txtname = $('#emotename'),     $txturl = $('#emoteurl'),     $txtusage = $('#emoteusage'); $txtname.val($txtname.val().replace(/(\r?\n){2,}/, '\n').replace(/^\r?\n|\r?\n$/, '')); $txturl.val($txturl.val().replace(/(\r?\n){2,}/, '\n').replace(/^\r?\n|\r?\n$/, '')); $txtusage.val($txtusage.val().replace(/(\r?\n){2,}/, '\n').replace(/^\r?\n|\r?\n$/, ''));

mind take @ particular article regarding jquery performance! :)

this should work great too, instead of repeating code, create array jquery objects , apply same replaces each of them.

var $objs = [         $('#emotename'),         $('#emoteurl'),         $('#emoteusage')     ];  $.each($objs, function() {     var $this = $(this),         val = $this.val();     $this.val(val.replace(/(\r?\n){2,}/, '\n').replace(/^\r?\n|\r?\n$/, '')); });

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
