如何在jquery或javascript中选择ID包含\\的元素

Question

we have some legacy code where Html element ID's are populated dynamically from database data (I cant change the data here) ex. <input type="text" id="2314/test/film/code\\branch"/>

when I get the ID from click event like below var src = window.event.srcElement; I get src.id= "2314/test/film/code\\\\branch";

I want to use the src.id to find the same element in different function like $(_element).find("[id='" + src.id + "']").get();

which is failing to get any ID since I see "\\" is replaced with "\\\\"

Please suggest me how to get around this ?

Answer 1

I don't think jQuery lets you use / in a selector. It is an illegal character in an id name, but still odd that jquery seems to flat out refuse it. Since JS has no problem with that selector You can select it with JS then pass it off to the jquery wrapper.

$(document.getElementById('2314/test/film/code\\branch'));

Maybe it´s works for you

$("[id='" + str.replace(/\\/g,'\\\\')  + "']").html(str)

Answer 3

反斜杠的正确正则表达式为'\\\\\\\\'。
