hidden

问题 I have a quick one that I'm struggling with after a long day! I have a form with a hidden field with the name of 'grant_cycle'. If the form is submitted after January 15, it should be give the value of 'Spring, [year]', or after July 15 should be 'Fall, [year]'. Could you kind people send me in the right direction, please? :-) Thanks! EDIT: Added year bits. 回答1: One option would be: retrieve the year of submission first create the date of January 15th in that year create the date of July 15th

问题 The idea: I'm setting the value of an input with type="hidden" via regular Javascript or jQuery. The issue: neither jQuery nor document.getElementById will find the hidden input, even though I'm absolutely sure the selector is correct and there are no conflicting elements. The code: I can't really post much of it, because it's full of rather complicated PHP that confuses me when I just look at it. Here's the javascript: $("#" + input.id.substr(0,2) + "_budget_hidden").val(budg_total); Note:

问题 I have some hidden input values that I would like to have be changed to a certain value once a user clicks on a link. 回答1: $('.someLink').click(function(){ $('.someHiddenInput').val('new value'); }); I think this is what you mean. HTML would look something like: <a href="#" class="someLink">click me to change value</a> <input type="hidden" name="hiddenVal" class="someHiddenInput" value="old value" /> 回答2: <input type="hidden" id="txtTextHdn" name="txtTextHdn" value="Y" /> <a href="#" id=

问题 Related fiddle Trying to build this neat little meter without a JS library (like Raphael), I came up with a question you can find here. After much frustration, I thought of another layout with which to make this meter work (that worked around a separate known Chrome bug as well), which can be seen at the fiddle above. <div id="clipper"> <div id="round"> </div> <div id="clipper2"> <div id="meter"></div> </div> </div> However, this created a completely NEW Android (4.0.4 at least) browser

问题 I have created a tool using jQuery that will show certain table rows depending on if certain checkboxes are selected. I am trying to have text that will display "3 Posters are required" for example. I am using the code below. In IE7 it is broken and instead of showing the number of < tr class="hidden"> that are visible , it is just showing the total number of < tr class="hidden">. Is there anything wrong with this code? $(".hidden").hide(); function countChecked() { var n = $("tr.hidden

问题 EDIT: so I changed the style.display to block and some of them worked. the internal and external textareas are coming back with element not found Another edit: In my CSS I had a display:none. When I remove this, it works. But thats no good as the element should only be available after an onclick. Why would setting it to display none stop it from ever being displayed? I have a simple script here. Basically I wanted to set all the contents of a panel to be invisible (document.style.display =

问题 I have a sequence of code where if C37 is blank, I want two series of rows to be hidden. The code I have works successfully for this. However, If D37 is not blank I would like the same series of rows to be unhidden.

问题 I'm trying to fetch a bunch of photo data from Flickr via a jQuery AJAX call using JSONP. I'd like to display n images at a time, then show the next n images each time the user clicks a button. I've read that one way is to add all the images to the DOM in the callback function and use the "hidden" CSS attribute to hide and reveal the next n images as the user clicks. Is this a recommended practice? 回答1: It depends entirely on what you're trying to do. If you create img elements and set their

问题 I have been using the following with no problems: $("#tableid tr:even").addClass("evenClass"); But now I have rows in my table that are hidden which messes up the zebra striping styles.
