JQuery :: Grab A Bunch Of HTML And Exhibit An Excerpt?
Sep 20, 2009
I've cobbled this script together to help me implement 'read more.[URL]... It does the job, but I lose all the mark-up in the process :[ It doesn't cater for a bunch of tags like <img>, <ol>, <ul> etc. slice()
ain't being too kind to me. // create a 'read more' link, and hide remaining text, if post content
The code is supposed to generate this: PS: This is generated by a PHP Function that the Ajax Load Method Calls.
[Code]...
I've been noticing a lot of problems when loading these stuff, Sometimes I have to remake the HTML Tags because its not showing anything. Is there any option? I want it to load EXACTLY how it is, I don't know if this is some kind of protection for bad code, but if it is I would like to disable. But also, this code is really clean. no problem, I don't know.
I'm currently trying to create a script which can grab the HTML from a web page and store it. For example, if I want to use google and search for the term "dogs", I want to be able to access that information.
How can I implement this in JavaScript, if at all?
I have written the code below. What it is supposed to do, is grab the HTML from a .NET panel (div) and make the changes and store them in a textbox, so that when the page is posted, the values are retained and can be re-read back to the .NET panel. I have found this script works in IE but doesn't work in FF. Now I know it is something I am doing wrong, but I can not work out what it is.
Code:
I have checked my syntax and I am sure it is correct. The only thing I can see that might be causing the problem is that I set final as the original and then I get the list of inputs.
From there I loop through and set the value of the inputs to the new values.
If I do an alert, the value shows what I would expect, but setting the store value as the final innerHTML doesn't appear to keep these values.
Could it be that once I pull the inputs from the final (placeholder = final.getElementsByTagName("input");) then changes I make to them do not affect the final variable?
So when a user goes to that directly, all the presets are already there? (since my updateResults function already sends that data along when the user is actually using the page, perhaps I could just somehow parse that url and call my updateResults function with the requested parameters...
I tried to enumerate through a index array to assign different ids to newly retrieved JSON data, the li element is initially set to be hidden and the hidden data can be seen from console. But the browser is failing to show the data when I tried to use ('li#a').animate({opacity: "show"}, "slow"); I also tried to use .animate right after each <li> appendTo the body and failed to show as well. I am wondering how to fix this? Is there any better way of handling this with out creating an enumerating array?
I'm trying to come up with a better architecture for dealing with multiple listeners in a multi-page questionnaire. Here's the general structure I'm looking to implement:
1. Set up CSS for animation
2. Look for preconditions
3. Initialize listener
4. Execute animation
Some issues to consider:
1. Some questions have dependencies that show or hide depending on what is selected in a parent question.
2. Needs to be IE 6 compatible.
3. It should be simple enough so that all you need to do is add a new question to a JSON object, which is what I have set up right now.
Some code (the looping structure that reads each question):
var newQ = eval(q); $.each(newQ, function () { // 1 - Setting CSS for each listener $(this.css).css({'width': '1500px', 'float': 'left', 'clear':'both'});
[Code].....
The problem here is that when I do a console.dir on $.each(this.value.length), it counts each character, as opposed to counting the number of elements in the array. Should I be doing an eval on q? Why or why not? If I could get this up and running, it would make my life 100x easier, as there are hundreds of questions, and I'd want to make this all data driven.
I'm not sure if I'm calling it the right thing, but I'm trying to dynamically create a bunch of key => value pairs in a javascript object.
Something like this:
Code JavaScript:
But the console gives me errors, and I haven't been able to find a way to do this. I've tryed putting the keys in square brackets, as was suggested somewhere online, but that didn't work.
Here's what I'd like to do using pure JavaScript and HTML (no Ajax or PHP): My website loads different JavaScript files dynamically which contain a bunch of data, that I will display on the website. The dynamical loading function is placed in the <HEAD> and looks like that:
Code: function loadJsFile(filename){ console.log("loading js file") var fileref=document.createElement('script') fileref.setAttribute("type","text/javascript") fileref.setAttribute("src", filename) fileref.onload = dataIsLoaded; if (typeof fileref!="undefined"){ document.getElementsByTagName("head")[0].appendChild(fileref) }}
The dataIsLoaded method in there is a callback that is triggered when the JavaScript file has been loaded: Code: function dataIsLoaded(){ console.log("loading js file done") dataLoaded = true; data = new Data(); }
DataLoaded is simply a global boolean that is per default false and the 'data' variable contains all the data I want to display on my site. While the JavaScript file is being loaded, the browser continues building the site. When it gets to the <body> that wants to access some information from the data variable, I get the unsurprising error that 'data' is undefined. I looked for a way to wait until 'data' is defined and then continue with building the <body> but couldn't find a solution.
Alternatively I wanted to reload the divs in the <body> when the 'data' is available: Code: function reloadDivs(){ if(dataLoaded){ console.log("data available, reloading divs"); document.getElementById('someDiv').innerHTML = document.getElementById('someDiv').innerHTML }else{ console.log("data is not yet available"); setTimeout('loadReportData();', 500); }} This does not work, I get a blank div when I do that.
I'm having two issues: First, is there an easier way for my showValue function to display the image file name without running a bunch of if statements? I tried doing something like document.getElementById('imgFile').value = imgArray[n]; but that did not seem to work.
Second, I'm trying to have the image file name change in my textbox when I click any button. I've accomplished this with onblur, but that only works if I click on the textbox. I'd like it to just change automatically.
I'm trying to grab a value passed in from a URL, i.e: test.html?foo=bar And I would like to grab the "foo" entry, with the value passed in. I'm guessing this can be done, but I can't find a way?
I'm trying to use the "selectable" feature - and need to find the IDs of the DIVs which have been selected. When I run the code below, all I keep getting is the ID of the first DIV in the selectable DIV (ie. 2011-01-01).
I am using the load() method to load navigation sections of hidden copy, which I will later grab and display. After the hidden copy loads, I am grabbing selected divs, and bringing them into an area where the copy will be displayed. My problem is that after I load the new copy, replacing the old copy, and I go to retrieve it, it gives me the old copy still (eventhough firebug shows me that the load() actually did bring in and replace the copy...so it's grabbing and displaying copy not even in the file anymore!) Why is this happening? the code is below.link to example: http:[url]....
$(document).ready(function() { $('#showcase_holder ul li:first').addClass("in_view"); $('#project_navigation ul li a').click(function(){[code].....
I have an <a> tag that inside it has text. I want to select just a certain area. For example lets say we have this: <a name="product">Apple Price:$5.00</a> Lets say I have that and I want to go to this tag named product and want to just grab $5.00. How can I do that. How can I convert that to a number?
Also, what if I want to change that price to $0.00 how would you do that? does jquery do regular expressions?
I need to do all that. be able to replace $5.00 the dollar amount to any other amount.
I also do want to grab the dollar value and use it as a number. To compute the total charges.How would one do this?
I use the following function to clear the value of input fields onfocus and reset them back to the original value if left empty. The problem is now I am trying to serialize a form that contains radio buttons, and the value is always empty, How can I modify this so it doesn't clear the value of input radio buttons?
I am not completely new to JQuery, but not a beginner either. Anyway, I want to do some advanced stuff like creating everything dynamically with JQuery. So here's the rough concept: Step 1: Information get's collected Step 2: Information will be written in divs, the divs will get an ID and will be displayed with .append() Step 3: Setting css-propertys with the div's ID. I can't grab the div which I created with .append.
Actually I can't access anything which was created with .append - for example if I want to get an .attr() - I can't do it with these elements. Is there a workaround or am I wrong: $("#site").append("<div class='container' id=' " + containerId + "'>" + containerId + "</div>"); $("#" + containerId).css({ "left" : positionX + "px", "top" : positionY + "px", "background-color" : "#F000FA"});
My question is located here:[URL]... what I have is div 1 this div 1 has <a> tags appended to this div. It's a list of items the client selected to buy. so I have these <a> tags. I want to generate a invoice or a summary of the order and append the new <a> tags in a new div we will call this div 2.
for example lets say I have 5 apples at $1 each ordered and 3 oranges at $5 each for one order placed In div 2 I want to go to div 1 and grab the text name of the item and only grab the names once. No need to have multiple of the same item names. I will then create a new <a> tag and then append it to that div 2. Inside these <a> tag will be something like: Apple amount order 5 total $5.00 Orange amount order 3 total $15.00 Total amount due: $20.00 so in div 1 there be lots of <a> tags and you will see at least 3 apples ordered but it be listed as aseparateitem.
In the invoice or summary of the order I want to sum up the order. So I just want to let the client know your ordering 3 apples at a total of $5 for those apples. You ordered 3 oranges at a total of $15 which makes the bill to come out to be $20 dollars.
how can I grab from the <a> tag list only text that hasn't been grabbed yet. I don't want to display the word apple 3 times since there are 3 times that the client selected to order. How can jquery filter such requests. I just want to grab the text or names of the items. Then display that name once. if that name appears more then once in the div 1 then in div 2 you will say just the item name once but show how many of that item you ordered.
I need to be able to send the variable a as GET. I'm posting this code not to a webserver, but an arduino (micro controller) and it only accepts GET data. I need to be able to grab that data and put it in the div called led8. This works when I use a php page as the backend, but the arduino only accepts GET.
I want to test if we could use jQuery for our mobile devices. Because of network-restrictions I need to run the jQuery Test Suite from my local Apache (the mobile device does not have any internet connection).
If I understood correctly I would have to grab the latest version from git and run a MAKE. Since I'm under XP that isn't possible that easy...
I wonder if someone could tell me where I am going wrong with this script. The original implementation of finding a DL list and separating it by dt | dd groups and making new DL's from them worked good. It found only one DL by getElementById.
The problem I am having is now to process multiple lists in which are found now by a unique class name on the DL instead of getElementById and only processing one DL. I'm not really sure how to explain where I am going wrong but here is the code....
