Hi is there any way to upadte cell value with no events (i dont want to use 'onClick' or others)?
The scheme is: user is filling form value, then clicks 'ok', and then value should be showed in cell in html table ?
thx in advance for all help
Well, you can use a link with href="javascript:myFunction()" instead of an onclick, but I'm not sure if that counts as an event :)
No, you need to hook up on an even to trigger it.
Since the user is going to click the Ok link anyways that seems to be the most relevant place to invoke your javascript from.
Create a div with an id around the content you would like to change.
Create a javascript function that sets the innerHTML of the above div.
Call the javascript function when the user hits the Ok link.

Sorry if I'm unclear or the title is unclear, my main language isn't english. I was wondering if it's possible to send out a tweet without having to 'confirm' , i have a code that, when you press a button it tweets something, but a pop up opens, so i was really looking for something that can help me but I couldn't find anything related to this topic.
document.querySelector('#postInfo').addEventListener('click' , function(){
this.href = 'https://twitter.com/intent/tweet/?text=HEY';
});
The hey text is temporary, it'll come as some data from the DB.
You may be aware of this, but you actually are able to "programatically" click objects through your code. You will have to use a querySelector to first select the button you are trying to "click" and then you will need to use the .click() method on the object. If you are trying to remove the object or button altogether, you will first need to get the element then use element.parentNode.removeChild(element); to remove the element itself.
long-time lurker here asking my first public questions because I am truly stuck.
I'm working on a hosted shopping cart platform so I only have access to add code in certain designated divs. I have a javascript code that I'm calling externally (because inline is bad unless you have to, right?)
So my issue is, There is a <select> dropdown that I do NOT have direct access to change HTML and the silly shopping cart platform didn't give it an id, only the name attribute is set.
I need to clear the <div id="result_div"> when the <select name="ShippingSpeedChoice"> drop-down is clicked so I have:
$("[name=ShippingSpeedChoice]").change(function(e) {
$("#result_div").empty();
});
It fires once, but that's it. My question is, how do I make it fire EVERY TIME the <select name="ShippingSpeedChoice"> is clicked?
Here's all the relevant javascript (in case it's preventing #result_div from clearing somewhere):
$("[name=ShippingSpeedChoice]").change(function(e) {
$("#result_div").empty();
});
$("#btn_calc").click(function(e) { /// onclick on Calculate Delivery Date button
Thanks in advance, any help is appreciated!
If you want something to happen every time the element is clicked, use .click() rather than .change(). The latter only fires if they select a different value from the menu than it had before.
$("[name=ShippingSpeedChoice]").click(function(e) { $("#result_div").empty(); });
First of all, I'd probably try and setup the shopping cart select to have an id.
$("[name=ShippingSpeedChoice]").id = 'shopping_cart_select';
then try binding the "change" function to the element via it's id.
$('#shopping_cart_select').bind('change', function(){
//rest of code goes here
}
I still wasn't able to use the name attribute to call the function, so I found a way around it by using the id of the td the ShippingSpeedChoice dropdown was in:
$("#DisplayShippingSpeedChoicesTD").change(function(e) {
$("#result_div").empty();
And it fires every time now. Thank you so much for all your feedback & assistance - I still wish I could figure out how to use the name attribute rather than the id, but that will be a puzzle for another day!
I am trying to append new returned data to my select tag when user selects a drop down menu
obj.prototype.getText=function(){
codes....
call ajax....
ajax.callback=function(data){
$('#option').append(data);
}
}
$('#dropdown').on('change', function(){
obj.getText()
})
My problem is that I only want to append data when the user clicks the dropdown menu the first time.
my code will keep append more same data to my #option as long as user keeps clicking the drop down menu...
Are there anyways to fix this? Thanks a lot.
Use .one() instead of .on(). It unbinds itself once you trigger the event once:
$('#dropdown').one('change', obj.getText);
You could simply remove the on change event, so it's no longer triggered.
$('#dropdown').off('change');
I would also look into the notion of a "run once" command. This isn't really what I would recommend here, but going forward, it's a cool thing to know. underscore.js does it well
You need to turn off the handler.
something like this.
$('#dropdown').on('change', function(){
obj.getText()
$('#dropdown').off('change');
})
That is probably the best way , turn of event handler , or you could always store a bool value in a hidden field , like
<input type="hidden" id="hidAleadyAppended" />
and then set it to true after it is appended once.
This way if you ever need to know if it has been appended already in other code, that is a quick reliable way to check
I have a SharePoint list with the following single line of text fields: Title, Year and Type or Location. I want to be able to hide the Type or Location table row in the default display form. I know that I should create a JavaScript script and put it in Content Editor web part inside DispForm.aspx.
I am not fluent with jQuery syntax, thus I need help with the code, i.e. I don't know how to reference the table row which contains Type or Location field and its value. Here's what I've done so far, but it doesn't work:
jQuery(document).ready(function($) {
$("input[title='Type or Location']").closest("tr").hide();
});
I know that the "input[title='Type or Location']" part is incorrect; at least I think it's that. Could anyone help me out? Thank you.
Try:
jQuery(document).ready(function($) {
$("h3.ms-standardheader:contains('Type or Location')").closest("tr").hide();
});
I am not sure why you want to use jQuery for that. In SharePoint, you can choose to make a field required, optional or hidden. In most cases, just switching to hidden will address your issue.
For the record, I would also try to avoid as much as possible the use of jQuery(document).ready, it might conflict with the SharePoint out of the box onload event. In your case it is not needed.
Update: here is a way to do this with jQuery:
$("td.ms-formlabel:contains('Type or Location')").parent().hide();
Try it this way:
jQuery(document).ready(function($) {
$("input[title='Type'],input[title='Location']").closest("tr").hide();
});
It depends what type of column Type ior Location is. If it's a Single line of text, then you're close. You should use a DOM inspector like IE's Developer Tools or Firebug to see what the actual title of the input element is.
If the column is a different type, then it's likely not an input element. Using the DOM inspector again, you can look at what elements make up the field control and decide on your selector from that.
Finally, remember that hiding things in script is not secure. A savvy user can turn off the script or otherwise change the script so that they can edit it. It all depends on your requirements.
// UPDATE //
Ah, you said DispForm. As was pointed out in another answer, there aren't any input elements in a DispForm. You need to correct your selector.
If its just the Default Display Form, How about just creating a view and making it default?
The syntax should be like this:
$("input[title='Type']").closest("tr").hide();
$("input[title='Location']").closest("tr").hide();
It will work.
I am currently using a javascript code to make an entire row in my table clickable. Once the row is clicked a function is ran, I am wondering what I can use to redirect to a PHP page and preferably send a post variable along with it. My guess is AJAX but I am not sure how or if it would work.
Javascript
function DoNav(theUrl) {
document.location.href = theUrl;
};
HTML
<tr onclick="DoNav('myphpscript.php');">
I have access to jQuery so that is also an option. Any help is appreciated, Thanks!
If you need to POST the data (not use GET), One easy option is to create a form element on the fly, attach input elements with the values you need and submit it. You can do that like so if you use jQuery:
$(function() {
$('tr').click(function() {
var mail_id = /* get the mail id of this row... not sure where since I dont' have the HTML */
$('body').append('<form method="post" action="myphpscript.php" id="donavform" style="display:none;"></form>');
$('#donavform').append('<input type="hidden" name="mid" value="'+mail_id+'" />');
$('#donavform').submit();
});
});
Hope that makes sense. If not, let me know! It's, okay...
Explanation:
The very first line is a jQuery shortcut way of saying "when the document is done loading..." So, when the page is done loading, I'm going to attach an event listener to all elements in the document. When one of those elements is clicked, we can then extract the mail id (and whatever else you need) that is in relation to that particular table row. So, if you had HTML like this:
<!-- 8435 is the mail ID in this example. -->
<tr id="row3">8435</tr>
Then we could extract the mail_id variable like so:
var mail_id = $(this).html();
Now, we are going to attach a hidden form element to the end of the body of the HTML (it doesn't really matter where we put it since it is hidden... so, the end is fine). In this form element, we set the method to POST and the action to whatever php file you need to POST to. I also set an ID so it's easily referred to in the next step.
I'm now going to select the newly-created form element using its ID and I'm going to append a new hidden input element to it with the appropriate name value pair.
$('#donavform').append('<input type="hidden" name="mid" value="'+mail_id+'" />');
Finally, I'm going to use the jQuery JavaScript submit method to trigger the submit event on the form. This is basically equivalent to pressing the 'submit' button on a normal form.
Try it out, it should work flawlessly.
If you're going to a new page, just submit the form as usual. Put the data in form fields (hidden if required). No need to Ajax, jQuery or any other magic unless you want to stay on the same page and post in the background.
If the amount of data is not ridiculously large, use a query string...
<tr onclick="DoNav('myphpscript.php?key=value');">
Or if you need a natural HTTP post, you can programmatically submit the form with Javascript...
onclick="document.forms[0].submit();"
You could send the data along in a cookie. There's a nice jQuery plugin that helps with setting cookies in the jQuery namespace.
