Jquery选择带斜杠的属性

Question

I'm trying to select an object with JQuery filtering by a value of an attribute that is a unique filename. I can't escape from slashes when the selector is made with a var. I lost 2 hours trying with multiple combinations but I think I'm missing something. Thanks in advance for the light

My HTML:

<table class="table table-condensed" id="CLKPMTable_2"><tbody><tr class="click-row" valuetype="PM" filename="\\server\folder\file1" paymentmethodid="1"><td class="col-md-1"><img width="24" height="24" src="/Content/img/123.png" id="PMURLIMG_"></td><td class="col-md-10" id="PM_FILENAME_">BO OCT</td><td class="col-md-1 text-right"><img width="16" height="16" src="/Content/img/notyet.png" id="PM_STATUS_"></td></tr><tr class="click-row" valuetype="PM" filename="\\server\folder\file2" paymentmethodid="2"><td class="col-md-1"><img width="24" height="24" src="/Content/img/visa.png" id="PMURLIMG_"></td><td class="col-md-10" id="PM_FILENAME_">O SEP</td><td class="col-md-1 text-right"><img width="16" height="16" src="/Content/img/notyet.png" id="PM_STATUS_"></td></tr></tbody></table>

My Javascript:

var filename = "\\server\folder\file1";
var selec = $('tr[valueType="PM"][filename="'+filename+'"]');
alert(selec.attr("paymentmethodid"));

Didn't work neither with:

var filenamescaped = filename.replace('\\','\\\\')
var selec = $('tr[valueType="PM"][filename="'+filenamescaped+'"]');

Also didn't work neither with (from: Jquery official doc to escape chars used in css ):

function jq( myid ) {
 return myid.replace( /(:|\.|\[|\]|,|=)/g, "\\$1" );
}

 var filename = "\\server\folder\file1";
  var filenamescaped = jq(filename);

My fiddler to make some test: jsfiddler

The value's backslash needs, in this case, to be doubled twice for it to work as a valid selector

 var filename = "\\\\\\\\\\\\\\\\server\\\\\\\\folder\\\\\\\\file1"; var selec = document.querySelector('tr[valueType="PM"][filename="'+filename+'"]'); alert(selec.getAttribute("paymentmethodid")); 

 <table class="table table-condensed" id="CLKPMTable_2"><tbody><tr class="click-row" valuetype="PM" filename="\\\\server\\folder\\file1" paymentmethodid="1"><td class="col-md-1"><img width="24" height="24" src="/Content/img/123.png" id="PMURLIMG_"></td><td class="col-md-10" id="PM_FILENAME_">BO OCT</td><td class="col-md-1 text-right"><img width="16" height="16" src="/Content/img/notyet.png" id="PM_STATUS_"></td></tr><tr class="click-row" valuetype="PM" filename="\\\\server\\folder\\file2" paymentmethodid="2"><td class="col-md-1"><img width="24" height="24" src="/Content/img/visa.png" id="PMURLIMG_"></td><td class="col-md-10" id="PM_FILENAME_">O SEP</td><td class="col-md-1 text-right"><img width="16" height="16" src="/Content/img/notyet.png" id="PM_STATUS_"></td></tr></tbody></table>

In your particular case the filename value need to be already escaped for the replace to work, as in var filename="\\\\\\\\server\\\\folder\\\\file1"

Do note the global switch in the replace command so it replace all occurrences

 var filename = "\\\\\\\\server\\\\folder\\\\file1"; var filenamescaped = filename.replace(/\\\\/g,'\\\\\\\\\\\\\\\\'); var selec = $('tr[valueType="PM"][filename="'+filenamescaped+'"]'); alert(selec.attr("paymentmethodid"));
