How do I pass a javascript parameter to an asp.net MVCmodel from within a View?
- by Josh
Hi everyone!
I am having an issue trying to access a list property on a model from within a javascript. My basic situation is this:
I have an ArticleController and an ArticleViewModel. An Article has a number of properties, one of which is Text, which is just a string that contains the contents of the article. The ArticleViewModel contains a Pages property, which is just a List of Strings. When the ArticleViewModel constructor is called, I populate the Pages list by dividing up the article text based on some delimeters.
I have a View which inherits the ArticleViewModel type. What I want to do is only display one page at a time, and then when the user clicks a page number (from a list at the bottom of the article), I want to use javascript to load that page into the #dynamicContent div.
The problem: I can't seem to pass a parameter to the Model.Pages property from within javascript... Is this possible? I get an error stating, "Expression Expected" when I try what I have below. I don't want to have to worry about AJAX calls or anything like that since I already have the entire article... I just need a way to access each individual page from within the javascript function.
Alternatively, if there is a better solution for "paginating" an article so that I can load each articlePage without having to refresh the entire html page, I would certainly be open to that as well.
Any help would be much appreciated!! Thanks for your time!
ArticleView Code:
Script at the top of the view:
function loadPage(pageNumber) {
try {
alert(pageNumber);
$('#dynamicContent').html('<%=Model.Pages(' + pageNumber + ') %>');
}
catch (e) {
alert('in here');
alert(e.description);
}
}
HTML for view:
[...]
<div id="articleBody">
<div id="dynamicContent">
<%=Model.Pages(0)%>
</div>
</div>
[...]
Page Links at bottom of page:
[...]
<div>
<ul style="display:block">
<li style="display:inline">
<a href="#articleTitle" onclick="loadPage(0)"> 1 </a>
</li>
<li style="display:inline">
<a href="#articleTitle" onclick="loadPage(1)"> 2 </a>
</li>
</ul>
</div>
