jQuery ID selector not working for IE7 (.show()/.hide())

Question

On jQuery load I'm trying to hide/show certain divs depending on condition. Everything works outside of IE7. I have broken it down and I have found that the following class selector will work:

$('.medication_div').hide();

But, the ID selector, which I need, does not (Note: I tried harding code values which did also not work.

//Get the name of the medication selected
var medication_selected = $("ul#medication_classes li:last-child p").text();
//Show the div associated with the selected medication card
$("#"+medication_selected).show();

Here is the HTML code generated after run:

<ul id="medication_classes">
            <li>
                <p>Celexa</p>
                <input id="Meds_0" name="Meds[0]" type="hidden" value="Celexa" />
            </li>

            <li>
                <p>Lisinopril</p>
                <input id="Meds_1" name="Meds[1]" type="hidden" value="Lisinopril" />
            </li>
        </ul>
        <div id="results_detail" class="grid_12 alpha">
            <ul>
                <li>

                    <div class="medication_div" id="Celexa">

            </ul>
        </div>

When hard-coding for the above example I have hard-coded to no avail:

$("#Celexa").show();

Any ideas?

Answer 1

Turns out the Rails code was generating an extra character which was only getting interpreted in IE7. To this point, I'm still not sure what the character is (possibly non-unicode), but I fixed the problem by using the jQuery wildcard selector:

$("div[id^="+medication_selected+"]").show();

Answer 2

worked fine on my ie7. inspect your css / style in firefox.

btw - try using json, templates and the jquery data for better results. for example:

HTML:

<p>select one:</p>
<ul id="medication_classes">
</ul>
 <div id="medication_detail">
<p>Protocol Set Triggering: <span class="data-protocol">General</span></p>
<p>Does the patient still have active refills for <span class="data-name">Celexa</span>?</p> 
<p>No:<input type="radio" value="No" />  Yes:<input type="radio" value="Yes" /></p>
<p>Approve the <span class="data-name">Celexa</span> refill as indicated in the patient record.</p>
<p>When was the dosage for this medication last changed?</p> 
<p><input class="date" /></p>
<p>Fill in the following as much possible in order to find the most relevant protocol.</p>

JS:

$(function () {
        var medications = [
            { name: 'Celexa', protocol: 'General' },
            { name: 'Lisinopril ', protocol: 'Hypertension Medications' }
        ];


        for (var medicationID in medications) {
            var medication = medications[medicationID];

            $('<li>')
                .data('medicineData', medication)
                .text(medication.name)
                .appendTo('#medication_classes')
                .click(function () {
                    var medicineData = $(this).data('medicineData');
                    $('.data-name').text(medicineData.name);
                    $('.data-protocol').text(medicineData.protocol);
                });
        }

    });

maybe use pure - which is a good templating engine.
