onclick trigger doesn't work first click

由 强颜欢笑 提交于 2019-12-02 05:00:47
问题 I'm confused why the onclick function doesn't register the first time it is clicked. Each div with the onclick trigger has to be clicked twice the first time. function selected(elmnt) { if (elmnt.style.backgroundColor == "transparent") elmnt.style.backgroundColor = "#990000" else elmnt.style.backgroundColor = "transparent" } #container { background-color: transparent; height: 100px; width: 100px; } <div id="container" onclick="selected(this)">click me</div> Am I missing something here? 回答1:

Javascript slide effect onclick

由 爱⌒轻易说出口 提交于 2019-12-02 04:57:43
I'd like to add a slide & fade effect to a DIV, with purely Javascript, using "onclick". The code is here: http://jsfiddle.net/TCUd5/ The DIV that has to slide has id="pulldown_contents_wrapper". This DIV is contained in a SPAN, that also triggers it: <span onclick="toggleUpdatesPulldown(event, this, '4');" style="display: inline-block;" class="updates_pulldown" > <div class="pulldown_contents_wrapper" id="pulldown_contents_wrapper"> And I think the JS code that controls the SPAN onclick is: var toggleUpdatesPulldown = function(event, element, user_id) { if( element.className=='updates

Onclick of a button run a function - not working?

由 白昼怎懂夜的黑 提交于 2019-12-02 04:53:43
html: <button id="go-btn">GO BUTTON!</button> javascript: function hi(){ alert("hi"); } document.getElementById("go-btn").onclick = hi(); When I refresh the page the alert pops up before I click the button. Why is this happening? Thanks a lot! Because you are calling it while the assignment: document.getElementById("go-btn").onclick = hi(); Just remove the () and you assign the hi -function to the onclick -handler. document.getElementById("go-btn").onclick = hi; Currently you are assigning the RESULT of hi() to the onclick -handler. Try this: function hi(){ alert("hi"); } document

由 只愿长相守 提交于 2019-12-02 04:45:16
I am using the following list layout for items that have associated comments . The number of comments are indicated by the box on the right side. Currently, I am using the onListItemClick handler to launch another details view. public class CustomListFragment extends ListFragment implements LoaderCallbacks<Cursor> { private Activity mActivity; private CursorAdapter mAdapter; private QueryParameters mQueryParameters; @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); setEmptyText("No data to display"); mActivity = getActivity(); if

Function doesn't execute from an onclick inside the html [duplicate]

由 混江龙づ霸主 提交于 2019-12-02 04:23:53
问题 This question already has answers here : JavaScript not running on jsfiddle.net (4 answers) Closed 5 years ago . this is probably stupidly easy but I'm very new to JavaScript and it's driving me nuts. My question, why doesn't this work: http://jsfiddle.net/Ye9tG/ <input type="button" id="butt" value="Button" onclick="getThought();"/> It works fine if I add the onclick directly into the JavaScript: document.getElementById("butt").onclick = getThought; Thanks in advance. 回答1: Your getThoughts

Calling A Button OnClick from a function

由 爱⌒轻易说出口 提交于 2019-12-02 04:17:28
问题 I have a button with OnClick=Button_Click. I want to call Button_Click from another function but the problem is that I need to give it: (object sender, EventArgs e) What should I enter for those parameters? Is there any way around it? 回答1: You could do this Button_Click(null,EventArgs.Empty); although I agree that it's better to extract function that could be called from anywhere. For example if you have protected void Button_Click(object sender, EventArgs e) { //some list of code } this code

Update hidden input value with onclick event from ajax drop down menu

由 十年热恋 提交于 2019-12-02 04:12:47
I'm working with MachForm and have this hidden field that I've added: <input type="hidden" name="element_273_price" value=""> I've integrated an ajax drop down menu that allows for an onclick event to be fired. I'd like the hidden field above to have a value inputted after the onclick event (onclick would tell the hidden field what the item was and price for that item) so that I can then pass it along through the rest of the JavaScript for the updating of the price on screen. Here's my code for calculating a text box: $('#main_body li[data-pricefield="text"]').delegate('input.text','keyup

How would I dynamically create input boxes on the fly?

由 ﹥＞﹥吖頭↗ 提交于 2019-12-02 03:31:06
I want to use the value of a HTML dropdown box and create that number of input boxes underneath. I'm hoping I can achieve this on the fly. Also if the value changes it should add or remove appropriately. What programming language would I need to do this in? I'm using PHP for the overall website. Here is an example that uses jQuery to achieve your goals: Assume you have following html: <div> <select id="input_count"> <option value="1">1 input</option> <option value="2">2 inputs</option> <option value="3">3 inputs</option> </select> <div> <div id="inputs"> </div> And this is the js code for your
