I have a popup, within the pop up is the following code, it contains a “container”, which forms a template:
<form method="post" class="signin" action="#">
<div id='container'>
<div>
<div id="divFeeTitle"></div>
</div>
</div>
</form>
I am populating the div via a container / for loop:
//go into JSON object and print out properties
for(var index=0; index<LineItem.length; index++){
DisplayTitle(LineItem[index]);
}
Display Title method does this:
function DisplayTitle(Object){
$('#divFeeTitle').html(Object.Title);
}
The trouble is, if there are 1+ objects, the divFeeTitle gets overwritten by the last object in the list. When if there are 1+ objects I need it to be laid out in order.
If I understand your issue correctly, you could try to use .append() instead of .html()
So your DisplayTitle function would look like:
function DisplayTitle(Object){
$('#divFeeTitle').append(Object.Title);
}
If you want to stop overwriting your data, be sure you save your data first:
var data = $('#divFeeTitle').html();
$('#divFeeTitle').html(data+Object.Title);
You can add an extra <br> if needed etc.

I have stored the results of $.get() into a variable called questionsdata. The data is basically a bunch of divs with unique ids. I wish to find just one div using an id. I can kind of understand that this wouldn't work but I don't know what would.
$(questionsdata).find("#593");
Example data in the variable:
<div id="591">Stuff</div>
<div id="592">Stuff</div>
<div id="593">Stuff</div>
<div id="594">Stuff</div>
You can parse HTML stored in a text variable with jquery quite easily - it doesn't need to be added to the DOM.
As #593 is at the top level, .find will not find as it searches children. Instead you could use .filter if it will always be at the top level, or wrap in another <div> - either at the source or via jquery:
var data = '<div id="591">Stuff1</div><div id="592">Stuff2</div><div id="593">Stuff3</div><div id="594">Stuff4</div>';
console.log($(data).find("#593").length)
// Use .filter
console.log($(data).filter("#593").text())
// Or wrap with a div
console.log($("<div>").html(data).find("#593").text())
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
var questionsdata = '<div id="x"><div id="a591">Stuff1</div><div id="b592">Stuff2</div><div id="c593">Stuff3</div><div id="d594">Stuff4</div></div>'
console.log($('#b592',questionsdata ).html())
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Your JavaScript
var data='<div id=591>Stuff</div>
<div id="592">Stuff</div>
<div id="593">Stuff</div>
<div id="594">Stuff</div>';
var $data = $(data).appendTo('#container");
var my_div=$("#container").find("#593");
Your HTML
< div id="container"></div>
Your CSS
#container{display:none;}
I recently found a code snippet that I would really like to understand:
var buttons = $('#fruit,#vegetable,#meat').click(function() {
$(this).toggleClass('active');
var classes = buttons.filter('.active').map(function() {
return this.id;
}).get().join(',.');
$('div.fruit,div.vegetable,div.meat').hide().
filter('.' + (classes || 'none')).show();
});
The HTML code :
<div style="float:right; padding:25px;">
<button id="fruit" class="active"><span>fruit</span></button>
<button id="vegetable" class="active">vegetable</button>
<button id="meat" class="active">meat</button>
</div>
<div>
<p>Trying to use buttons as an "or" case rather than "and." When choosing fuit or vegetable, I want to see tomato as part of each list, <em>not just</em> when both are selected.</p>
<div class="fruit">
<p>apple</p>
</div>
<div class="vegetable">
<p>pumpkin</p>
</div>
<div class="vegetable">
<p>okra</p>
</div>
<div class="fruit">
<p>orange</p>
</div>
<div class="meat">
<p>beef</p>
</div>
<div class="fruit vegetable">
<p>tomato</p>
</div>
</div>
The fiddle is here.
I do understand how all the methods work in jQuery like toggleclass, filter and map, I also understand how join works in JS, but in this particular example, I am not able to figure out how get() is working or rather what is it's usage in the script is.
I went through the jQuery documentation for get() and I came across this method for the first time; to me, it seems it's very much similar to eq() in jQuery, but I am still not able to figure out why exactly get is being used in my example.
Can somebody explain this to me ?
.get is used here, because .map returns a jquery style object which contains some functions and information about the contained data. But in this scenario only the values stored within the object (the class names of the active buttons) are wanted. .get is used to get an array containing the raw values and with .join(",.") the values from the array get concatenated to a string. This string then get's used to show all div's that should be active according to the selected buttons.
I have the following HTML to repeat the elements of some arrays that are in a javascript object:
<div ng-repeat="info in pTab.infoData">
<p>{{info}}</p>
</div>
<div ng-repeat="stats in pTab.modelData">
<p>{{stats}}</p>
</div>
Here is the relevant chunk of the javascript object with infoData and modelData:
As you can see, infoData and modelData are both at arrays, both at the same level, and both referenced the same ways in the HTML.
Why then, do the elements of infoData display on my page while the elements of modelDataare nowhere to be found?
If you need more HTML, js, or a view of that full object, please let me know. Thank you so much for your time.
I want to search multiple HTML files from a separate page, where I search for text from all the divs which has a specific id for each, whole id containing matched search term will be displayed on the search page in list.
The div list looks like this :
<body>
<div class='vs'>
<div id='header 1'>content 1 here </div>
<div id='header 2'>another text </div>
<div id='header 3'>whatever </div>
</div>
</body>
Please note that I want to perform search from different page and want to display results there with links to the searchable page.
For now I was searching like this :
HTML
<body>
<input type="text" id='search' />
<div class='vs'>
<div id='header 1'>content 1 here </div>
<div id='header 2'>another text </div>
<div id='header 3'>whatever </div>
</div>
</body>
JavaScript
$('#search').on('input', function () {
var text = $(this).val();
$('.vs div').show();
$('.vs div:not(:contains(' + text + '))').hide();
});
It is working on the fiddle here, but I don't want it to work like this, I want to do the search from a separate page remotely and display results there with link to this page.
Solution with jQuery and AJAX:
<form id="searchForm">
<input type="text" id="search"/>
<input type="submit" name="Search!" />
</form>
<div id="resultContainer">
</div>
<script type="text/javascript">
$("#searchForm").submit(function(e) {
e.preventDefault();
var results = $("#resultContainer");
var text = $("#search").val();
results.empty();
$.get("http://example.com/", function(data) {
results.append($(data).find("div:contains(" + text + ")"));
});
});
</script>
Fiddle (This fiddle enables you to search for content on the jsfiddle page, try for example JSFiddle as search term.)
Note however that this does not work cross-domain, because browsers will prevent cross-site scripting. You didn't describe your use-case clear enough for me to know whether you're okay with that.
You'll want to look at using PHP file_get_contents to retrieve the HTML contents of the external page, and from there analyze the data in the <div>s that you are interested in. Ultimately, you'll want to store each individual search term in a JavaScript array (you can create JavaScript arrays dynamically using PHP), and then create search functionality similar to example you posted to search all the elements in your array.
So on page load, you'll want to have a <div> in which you are going to list all the elements from the array. You can list these by looping through the array and displaying each individual element. From there, you will want to call a function every time the user enters or deletes a character in the <input> box. This function will update the <div> with an updated list of elements that match the string in the <input> box.
This is the theory behind what you are trying to accomplish. Hopefully it will give you some direction as to how to write your code.
Update:
If you're looking for a JavaScript only solution, check out a JavaScript equivalent of PHP's file_get_contents: http://phpjs.org/functions/file_get_contents/
From here, you can maybe look at using .split to break up the list. Ultimately, you're still trying to store each individual search term as an element in an array, it's just the method that you retrieve these terms is different (JavaScript as opposed to PHP).
Perhaps I was emphasizing too much on PHP, perhaps it's because it's the web development language I'm most familiar with. Hope this JavaScript-only solution is helpful.
I am using jQuery and bootstrap to give drop-down search suggestions.Following is the html code.But when I type something in the search form and then clear the form.Two forms apears as in the picture.Why? I am new to jQuery. Thanks for any help.
<div class="container">
<div class="row">
<div class="span6 offset3">
<form class="form-search">
<input type="text" id="month" name="month" class="input-medium search-query">
<button type="submit" class="btn">Search</button>
<div id="suggestions">
</div>
</form>
</div>
</div>
</div>
<script>
jQuery("#month").keyup(function(){
ajax('search', ['month'], 'suggestions')});
</script>
EDIT:
I am using web2py framwork.This is the search function's code:
def search():
if not request.vars.month: return dict()
month_start = request.vars.month
selected=complete('piracyfinder',month_start) #this line get the search results
return DIV(*[DIV(k['title'],
_onclick="jQuery('#month').val('%s')" % k['title'],
_onmouseover="this.style.backgroundColor='lightblue'",
_onmouseout="this.style.backgroundColor='white'"
) for k in selected])
It appears you are using the same function (i.e., search()) to fill in the suggestions as well as to create the form (though that function doesn't process the form when submitted). According to the logic, when request.vars.month is either empty or does not exist, the function returns an empty dict. This will result in the associated view (i.e., /views/[controller name]/search.html) being executed and returned. Presumably the search.html view contains the HTML code shown above. So, when you clear the input box, the keyup handler is triggered and sends an empty month variable, which results in a new copy of the form being sent back and inserted in the "suggestions" div. You can avoid this problem by checking whether request.vars.month exists:
if not request.vars.month:
return '' if 'month' in request.vars else dict()
A better approach might simply be to use different functions for the search form and the suggestions given that they do completely different things and don't share any code.
if not request.vars.month also applies to the month var existing but being empty. Therefore, it's returning the form.
You need to do one of these:
Have your "suggestions" code be in a different page/file
Add a isAJAX variable to the request (or some other way to identify AJAX requests)
Check if the variable exists, rather than checking if it is falsy.
