My template crashes with 500 - Internal server error. when I attempt to use the range functionality that's part of jsRender. Any advice would be much appreciated.
Sample code
{{range start=1 end=10}}
<option>data</option>
{{/range}}
or
{{range start=0 end=:data }}
<option>data</option>
{{/range}}
range is not a native jsrender tag. It is just used in the sample showing jsrender custom tag. However you can achieve such a behavior simply with custom helper function and for tag.
helper function
function range(start, end) {
return _.range(start, end);
}
content
{{for ~range(0, 10)}}
<h1>{{:#index}}</h1>
{{/for}}

I am new using Office UI Fabric JS, and I have just imported a SearchBox by following the steps here.
But how do I obtain the query and perform the search when the user hits enter? I have a search function already written in javascript, but I do not know where to call it. Is there some onSearch like property for the SearchBox?
Also, what exactly is happening within the <script>...</script> tags? I am not able to figure out what the following line means from the above link.
Add the following <script> tag to your page, below the references to Fabric's JS, to instantiate all SearchBox components on the page
Okay so here is what I did.
First you add an id element in the HTML for the input field.
<input class="ms-SearchBox-field" type="text" value="", id="searchText">
Then in my JS file, I added the following:
$('#searchText').on("keypress", function (e) {
if (e.which == 13) { // 13 is for enter
// call search function here
}
});
I was using JQuery already so it helped.
I am using razor to show/hide page content based on variables in the model:
#if (Model.TicketShown == null)
{
#:<div id="ticket-section">
} else {
#:<div id="ticket-section" style="display:none">
}
//More Code
#:</div>
I have been using it for a while, but today I am getting the error '"#" must be followed by a valid code block' just on the closing tag. I am using the syntax elsewhere and it works fine.
Why and is there a more elegant way of doing this? Thanks
#: is meant to be used inside code blocks (see Explicit line transition), your #:</div> might not be inside one. You could use Html.Raw as alternative (e.g. #Html.Raw("</div>")).
With the help of the ?: operator, you could also rewrite the if as follows:
<div id="ticket-section" style=#(Model.TicketShown == null ? "" : "display:none")>
...
</div>
I'm trying to make a blog using Vue as laid out in the excellent demo here. I'd like to include some mathematical formulas and equations in my blog, so I thought I'd try to use vue-katex. vue-katex formats my mathematical notation perfectly when I put all my KaTeX HTML directly into my Vue templates, but to create a useable blog I need to keep my content separate from my templates (as shown in the demo).
I can't get vue-katex to format HTML content in the static folder. That's what I'd like help with.
Setup
I cloned the github repo for the demo.
I added vue-katex to package.json:
"vue-katex": "^0.1.2",
I added the KaTeX CSS to index.html:
<!-- KaTeX styles -->
<link
rel="stylesheet"
href="https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.9.0-alpha2/katex.min.css"
integrity="sha384-exe4Ak6B0EoJI0ogGxjJ8rn+RN3ftPnEQrGwX59KTCl5ybGzvHGKjhPKk/KC3abb"
crossorigin="anonymous"
>
I added the import statement to src/App.vue:
import Vue from 'vue'
import VueKatex from 'vue-katex'
Vue.use(VueKatex)
and I added a simple line of HTML with KaTeX to the BlogPost template:
<p>Here's an equation in the actual Vue template: <div class="equation" v-katex="'X \\sim N(\\mu, \\sigma^2)'"></div></p>
As I said, this works - I see formatted mathematical notation in my blog post (URL http://localhost:8080/read/neque-libero-convallis-eget):
However, I need different equations for every blog post, of course.
So I tried adding KaTeX HTML to the "content" field in the JSON for the first blog post: static/api/post/neque-libero-convallis-eget.json. I changed the "content" line to:
"content": "Here's an equation in the static folder: <div class=\"equation\" v-katex=\"'X \\sim N(\\mu, \\sigma^2)'\"></div>",
This content appears on the page, but the equation doesn't render. I see this: (the text appears but no equation is shown)
When I use Developer Tools to inspect the HTML on the page, I see this:
You can see that vue-katex has been applied to the equation I put in the template directly: it has parsed the HTML I typed into lots of spans with all the mathematical symbols, which are showing perfectly.
However the KaTeX HTML I've added to the "content" in the static folder has simply been placed on the page exactly as I typed it, and is therefore not showing up as an equation on the page. I really need to keep my blog post content in this static folder - I don't want to have to create a different .vue file for each blog post, that defeats the point!
My question is: is there a way to manually "apply" vue-katex to the HTML I place in the static folder, when it loads? Perhaps there is something I can add to the plugins/resource/index.js file, since this contains the function that loads the data from the static folder?
Many thanks in advance for any help.
*Disclaimer: I'm definitely no expert / authority on what I'm about to explain!
One thing to remember is that Vue reads the templates you write, and then replaces them as reactive components. This means that although you often write Vue attributes like v-for, v-html or in this case v-katex these attributes are only useful up until the app or component is mounted.
With this in mind, if you have a Vue app that ajax loads some html, its not going to be able to rerender itself with those Vue bindings in place.
I have somewhat ignored your current set up and set about solving the issue in another way.
Step 1: Reformat your data from the server side
I've put the posts into an array, and each post contains the template (just a string of html) and the equations separately as an array. I've used [e1] in the post as a placeholder for where the katex will go.
var postsFromServer = [{
content : `<div>
<h2>Crazy equation</h2>
<p>Look here!</p>
[e1]
</div>`,
equations : [
{
key : 'e1',
value : "c = \\pm\\sqrt{a^2 + b^2}"
}
]
}];
Step 2: When the post is rendered, do some work on it
Rather than just use v-html="post.content", I've wrapped the html output in a method
<div id="app">
<div v-for="post in posts" v-html="parsePostContent(post)">
</div>
</div>
Step 3: Create a method that renders all the katex, and then replaces the placeholders in the post
methods : {
parsePostContent(post){
// Loop through every equation that we have in our post from the server
for(var e = 0; e < post.equations.length; e++){
// Get the raw katex text
var equation = post.equations[e].value;
// Get the placeholder i.e. e1
var position = post.equations[e].key;
// Replace [e1] in the post content with the rendered katex
post.content = post.content.replace("[" + position + "]", katex.renderToString(equation));
}
// Return
return post.content;
}
}
Here is the whole set up, which renders Katex:

I created a custom html tag and it's firing on my completion order page however I can't seem to get the {{Total Amount}} to pull. This is a variable we created and it works with adwords conversion tracking tag but I can't seem to get it to pull in the amount using this custom html tag.
<script type="text/javascript">
var money = {{Total Amount}};
document.writeln('<img src="https://app.bronto.com/public/?q=stream_conversion&fn=Mail_Conversion&id=userid&type=$&description=sale&money='+money+'" width="0" height="0" border="0" alt="brontoconversiontracking"/>');
</script>
Can you please explain to me if I'm missing a step?? This is the only code we use to push the amount from the conformation page which is stored in ssp applications order_wizard_cart_summary.txt it pulls in the subtotal for Adwords conversion tracking but not the custom html script.
<script>
dataLayer.push({'subtotal':'<%= summary.total_formatted %>'});
</script>
I have a Total Amount dataLayer variable in google tag manager and the "Data Layer Variable Name" is subtotal.
If you make push() to dataLayer after the macro is used you'll get no data. Try debug mode to see the state of your variable.
I got it to work like this guys,
<script>
var price = '<%= summary.total_formatted %>';
var pri = price.replace("$","");
dataLayer.push({'subtotal':pri});
</script>
works prefect :)
I have two Hyper Links on to a DOJO DIv
var create = dojo.create("div",{
id:"create_links",
className:"iconRow1",
innerHTML:"<a class='popupLink' href='javascript:openCreateDialog()'>Create </a> <span>|</span><a href='javascript:openUploadDialog()'>Batch </a>"
},dojo.query(".ui-jqgrid-titlebar")[0]);
On click of the Batch Hyperlink , i have a function
function openUploadDialog()
{
// Here i want to disable the Create Hyper Link tried this way
dojo.byId('create_links')[1].disabled=true; // Not working
}
See whether i can answer your question.
HTML Part:
<div id="create_links">
g
h
</div>
JS Part:
dojo.addOnLoad(function() {
var a = dojo.query("#create_links a")[1];
dojo.connect(a,'click',function(e){
console.log(e.preventDefault())
})
})
#Kiran, you are treating the return of dojo.byId('create_links') like an array when that statement will return to you a node on the dom.
Also, hyperlinks don't support a disabled attribute to prevent them from being actionable. You could probably create a click handler that returns false to accomplish this type of functionality, or like #rajkamal mentioned, calling e.preventDefault(). #rajkamal also provides a good solution to selection the link properly.
