I am so close to getting this. Here's my code that is returning the correct url, but only when button is double-clicked. I only need one click to retrieve the image.
var origin = 'COMP';
var area = 'US';
var type = 'typeA';
var level = 'Xnay';
var time = '0';
var btn1 = document.getElementById("redbutton").winControl;
function change_area(new_area) {
area = new_area;
}
function change_type(new_type) {
type = new_type;
}
$(btn1).click(function () {
var src = "http://somesite.net/folder/WEB_" + origin + "_" + area + "_" + level + "_" + type + "_" + time + "HR.png";
change_area('GB');
change_type('typeB')
$('#mainmap').attr('src', src), false;
});
You try by adding
$(document).ready(function() { }); block
before the following line
$(btn1).click(function () {
Finally as,
$(document).ready(function() {
$(btn1).click(function () {
var src = "http://somesite.net/folder/WEB_" + origin + "_" + area + "_" + level + "_" + type + "_" + time + "HR.png";
change_area('GB');
change_type('typeB')
$('#mainmap').attr('src', src), false;
});
});

I have the follwoing Jquery code to open page on button click passing a parameter but ? is translated to %3F is there anyways to fix this?
$("#PrintDocument").click(function () {
var grid = $("#Billings").data("kendoGrid");
var row = $("input:checked", grid.tbody).closest("tr");
var item = grid.dataItem(row);
window.location.pathname = '/invoice/billing/Print' + '?productId=' + item.ProductID + '&' + 'runId=' + item.RunID;
});
You are setting the pathname which does not have a query string.
window.location.href = '/invoice/billing/Print' + '?productId=' + item.ProductID + '&' + 'runId=' + item.RunID;
I want to get all text posts of a Tumblr blog with jQuery getJson using Tumblr's API.
I tried using the following code, but I just got 20 posts:
function loadPosts () {
var key = "api_key=xBcVPLfdDKpH0GjMCd1whW7rPoYkzLgZD3ZwpzndISFI4huSpA"
var api = "https://api.tumblr.com/v2/blog/only-text-posts.tumblr.com/"
var post_amount
$.getJSON(api + "info?" + key,function(data) {
post_amount = data.response.blog.posts
$.getJSON(api + "posts/text?&filter=text&limit=" + post_amount + "&" + key,function(data) {
$.each(data.response.posts, function(i, item) {
var content = item.body
$("#Posts ul").append('<li>' + content + '</li>')
});
})
})
}
Here is a good sample Tumblr blog for testing:
http://only-text-posts.tumblr.com/
According to the documentation, only up to 20 posts are returned. You can specify an offset with the offset parameter, and retrieve all posts with several calls:
function loadPosts () {
var key = "api_key=your_key";
var api = "https://api.tumblr.com/v2/blog/only-text-posts.tumblr.com/";
var retrieve_more = function (offset) {
$.getJSON(api + "posts/text?callback=?&filter=text&limit=20&offset=" + offset + "&" + key,function(data) {
$.each(data.response.posts, function(i, item) {
var content = item.body;
$("#Posts ul").append('<li>' + content + '</li>')
});
if (data.response.posts.length == 20) {
retrieve_more(offset + 20);
}
});
};
retrieve_more(0);
}
loadPosts();

As from the Tumblr Api documentation there is a limit of 20 posts per request. You can perform multiple requests with an increasing offset.
var max_posts_per_page = 20;
$.getJSON(api + "info?" + key,function(data) {
post_amount = data.response.blog.posts;
for (var offset = 0; offset < post_amount; offset += max_posts_per_page) {
$.getJSON(api + "posts/text?&filter=text&limit=" + max_posts_per_page + "&offset=" + offset + "&" + key,function(data) {
$.each(data.response.posts, function(i, item) {
var content = item.body
$("#Posts ul").append('<li>' + content + '</li>')
});
});
}
});
Here's my code for gathering titles/posts from reddit's api:
$.getJSON("http://www.reddit.com/search.json?q=" + query + "&sort=" + val + "&t=" + time, function (data) {
var i = 0
$.each(data.data.children, function (i, item) {
var title = item.data.title
var url = item.data.url
var id = item.data.id
var subid = item.data.subreddit_id
var selftext = item.data.selftext
var selftextpost = '<p id="post' + i + '">' + selftext + '</p><br>'
var post = '<div>' + '' + title + '' + '</div>'
results.append(post)
results.append(selftextpost)
i++
});
});
Basically every post (selftext) is assigned a different paragraph id (post0, post1, post2, etc) for every result that's pulled. I'm also going to create a "hide" button that follows the same id scheme based on my i variable (submit0, submit1, submit2, etc). I want to write a function so that based on which button they click, it will hide the corresponding paragraph. I've tried doing an if statement that's like if("#hide" + i) is clicked, then hide the corresponding paragraph, but obviously that + i doesn't work. How else can I tackle this?
Could you try something like the below?
showhide = $("<a class='hider'>Show/Hide</a>");
results.append(showhide);
$(showhide).click(function() {
$(this).next().toggle();
}
Alternatively:
$.each(data.data.children, function (i, item) {
var title = item.data.title
var url = item.data.url
var id = item.data.id
var subid = item.data.subreddit_id
var selftext = item.data.selftext
var selftextpost = '<p id="post' + i + '">' + selftext + '</p><br>'
var showhide = $("<a class='hider" + i + "'>Show/Hide</a>");
var post = '<div>' + '' + title + '' + '</div>'
results.append(post)
results.append(selftextpost)
results.append(showhide);
$(showhide).click(function() {
$(this).next().toggle();
});
i++
});
I have a few cascading dropdowns on the bottom of my php page. Each time a user selects an option from the dropdown the following function is called to add the value of that option to my url variables. Currently the page refreshes to the top each time which is a huge problem. Normally I would use something like onCLick="window.location='page.htm#bottom';" to refresh to the bottom of the page but the below function stops working when I add the #bottom. Can someone help me adjust this function or give me other ideas that will refresh to the bottom of the page when the function is done.
function reload5(form){
if(document.getElementById('fda1').checked) {
var fda = '1';
}else if(document.getElementById('fda0').checked) {
var fda = '0';
}
var val=form.category.options[form.category.options.selectedIndex].value;
var val2=form.subcat.options[form.subcat.options.selectedIndex].value;
var val3=form.subcat1.options[form.subcat1.options.selectedIndex].value;
var val4=form.subcat2.options[form.subcat2.options.selectedIndex].value;
var comp1=form.mname.options[form.mname.options.selectedIndex].text;
var itemnum=document.getElementById('item').value;
var desc=document.getElementById('desc').value;
var quan=document.getElementById('quan').value;
var list=document.getElementById('list').value;
var uom=form.uom.options[form.uom.options.selectedIndex].text;
self.location='add_products.php#bottom?fda=' + fda + '&desc=' + desc + '&quan=' + quan + '&list=' + list + '&uom=' + uom + '&item=' + itemnum + '&cat=' + val + '&cat2=' + val2 + '&cat3=' + val3 + '&cat4=' + val4 + '&comp=' + comp1 ;
}
So this doesn't work: self.location='add_products.php#bottom?fda=' + fda
But this does : self.location='add_products.php?fda=' + fda
Any idea where to put the #bottom?
The issue is that the hash must come after the query string at the end. See this article. Try this... (I also cleaned up the code)
function reload5(form){
var val=form.category.options[form.category.options.selectedIndex].value,
val2=form.subcat.options[form.subcat.options.selectedIndex].value,
val3=form.subcat1.options[form.subcat1.options.selectedIndex].value,
val4=form.subcat2.options[form.subcat2.options.selectedIndex].value,
comp1=form.mname.options[form.mname.options.selectedIndex].text,
itemnum=document.getElementById('item').value,
desc=document.getElementById('desc').value,
quan=document.getElementById('quan').value,
list=document.getElementById('list').value,
uom=form.uom.options[form.uom.options.selectedIndex].text,
fda;
if(document.getElementById('fda1').checked) {
fda = 1;
} else if(document.getElementById('fda0').checked) {
fda = 0;
} else {
fda = -1;
}
window.self.location.href = 'add_products.php?fda=' + fda + '&desc=' + desc + '&quan=' + quan + '&list=' + list + '&uom=' + uom + '&item=' + itemnum + '&cat=' + val + '&cat2=' + val2 + '&cat3=' + val3 + '&cat4=' + val4 + '&comp=' + comp1 + "#bottom";
}
What I don't understand is why you are not doing something with Ajax that would not cause the page to refresh at all.
After replacign the location with new parameters, the page after loaded doesn't get the paramaters value, despite there are values in the parameters
the used code is :
function getURLParameter(name) {
return
decodeURI((RegExp(name + '=' + '(.+?)(&|$)').exec(location.search) || [, null])[1]);
}
$(document).ready(function () {
$(".sub").slideUp();
var div = getURLParameter("div");
var ddl = getURLParameter("ddl");
alert(div);
// alert("ManageTrainingNeeds.aspx?div=" + div + "&ddl=" + ddl);
// $("#" + div).slideDown();
// $("#ddlObjectiveGroup").val("'" + ddl + "'");
});
$(".btnAddSub").live("click", function () {
var diva = $(this).parent().parent().parent().parent().parent().parent().attr("id");
var ddl = $("#ddlObjectiveGroup option:selected").val();
window.location.replace("ManageTrainingNeeds.aspx?div=" + diva + "&ddl=" + ddl);
});
this alert(div); return undefined.. despite the div vairable in click event has a value
Try encoding the parameters and also canceling the default action in the click event:
function getURLParameter(name) {
return decodeURIComponent((RegExp(name + '=' + '(.+?)(&|$)').exec(location.search) || [, null])[1]);
}
$(document).ready(function () {
var div = getURLParameter('div');
var ddl = getURLParameter('ddl');
alert(div + ' ' + ddl);
});
$('.btnAddSub').live('click', function () {
var diva = encodeURIComponent($(this).parent().parent().parent().parent().parent().parent().attr('id'));
var ddl = encodeURIComponent($('#ddlObjectiveGroup').val());
window.location.replace('/ManageTrainingNeeds.aspx?div=' + diva + '&ddl=' + ddl);
return false;
});
Instead of fiddling with the URLs yourself, you could use a library for the job - such as URI.js. (sorry for the self-promo)
$(document).ready(function () {
var search = URI().search(true);
alert(search.div + ' ' + search.ddl);
});
$('.btnAddSub').live('click', function (e) {
var uri = URI('/ManageTrainingNeeds.aspx');
uri.search({
diva: $(this).parent().parent().parent().parent().parent().parent().attr('id'),
ddl: $('#ddlObjectiveGroup').val()
});
window.location.href = uri.toString();
e.preventDefault();
});
