Question

How can I get the ID of a paragraph when I pass text “Selection List” or “Deletion List”.

"<p id="section_548540600_title" class="CollapseExpand CollapseExpand_active" title="Collapse / Expand"><a href="javascript:void(0);">Selection List</a></p>"

"<p id="section_362548963_title" class="CollapseExpand CollapseExpand_active" title="Collapse / Expand"><a href="javascript:void(0);">Deletion List</a></p>"

Answer 1

Assuming I’ve understood your question correctly, you can use the :contains selector to match elements based on their text content:

// Where `someString` is "Selection List" or "Deletion List":
var id = $("p:contains('" + someString + "')").attr("id");

Update

Note that the above approach assumes you only have a single element containing each string. If there are other elements containing the same strings, you may need a different approach to ensure the element contains only that string:

var id = $("p").filter(function () {
             return $.trim($(this).text()) === "Test";
         }).attr("id");
