问题 Im trying to send a value of a dropdown on change to a php script. But with my way of solving the problem, the form and also the status String are posted twice.

问题 I am trying to automate some bit of IE, I'm successfully so far but got stuck with clicking on a dropdown from the IE dropdown as it is having a change event. I was able to click on the dropdown but unable to make the selection from the dropdown. The code I'm trying to input the value is working but change event is not working.

问题 I have three options and if you click on an option a checkmark shows over it, representing the option as selected. I have a limit of 1 set. As of now, the image/current checkmark input needs to be clicked again to remove it, rather than simply being able to click on another option and removing it. I tried to setup a snippet that replicates what I actually have, but the checkmark isn't showing for some reason. Regardless, I am attempting to incorporate a solution I saw from another post with

问题 I have a series of checkboxes and input type="text" areas, wherein I need to have the state of the checkbox set to true when the value in the text area changes. Simple enough. I've done this successfully: <input name="fixed" type="checkbox"> <input name="stuff" type="text" onchange="this.form.fixed.checked=true"> Which works fine. You have to edit the field then click out of it, but that is fine for my needs: ...but when I switch to this: <input name="fixed[0]" type="checkbox"> <input name=

问题 EDIT Note on the user experience... After the first comment I'd like to point out that every submit leads to a POST/redirect/GET and take the user to a new page.

And then if he clicks on the back button he sees his previous page, as it was before its checkbox was checked. The user never notices that his checkbox changes its state, because he's taken

问题 I have a list I want a filter, I have the checkboxes working as shown in this question. On my page I already had the tabs at the top of the page working as shown in the below code and in this fiddle. However they conflict with each other, so currently if you click on xtr1 while the checkbox for col 1 is clicked it removes all col 1 and shows all xtr1. I want it to be to show all of xtra1 that have col 1 ticked for example. I tried to handle this by adding the variable addchosen as shown below

问题 I'm trying to make a dropdownlist of the months. When the user select a month, the javascript fills the setter with the chosen value. Now I want to use that value above. So I made a form around my select with the action 'Onchange' and use the getMaand to calls the chosen month. Is there something wrong with the form? Because when I put this in comment, I get the dropdownlist with the months, when I put it in code, he prints every month in one line. I'm not an expert in Java, is it correct to

问题 Can i use a .jsp file as a parameter for onChange in a dropdownlist?

问题 I'd like my date to get saved anytime I change my date via ajax, is this possible? I tried <%= form_for @dates,:remote => true do |f| %> <%= f.date_select :booking_date,:onchange => "this.form.submit();" %> <% end %> but it does nothing, any good work arounds? 回答1: From the rails documentation: date_select(object_name, method, options = {}, html_options = {}) Because onchange is an html option you need to provide an empty set of options to date_select, otherwise it assumes onchange is a date

问题 I don't know what I'm doing wrong. I've found fixes/hacks for this but none of them seem to be working. Trying to use a single button/image (something) instead of the input-file control. It works so far except for in internet explorer. In ie the 'select file' dialog appears, lets you choose a file, the accompanying textbox gets populated but the change event doesn't fire. I've tried focus, blur, live, onpropertychange, change, onchange... but they just won't work. Any help? jQuery: $(function
