Adding dynamic value to a function

Question

I am trying to implement a plugin:

$(".myTbl th:nth-child(1)").truncate({
        width: "200",
        after: "&hellip;",
        center: false,
        addtitle: true
});

Instead of using a fixed value for width, I have a script that calculates it dynamically and sets it into a a variable, but when I plug it in the code breaks. What am I missing? it is all withing PHP code

echo '

var myWidth = 150;

$(".myTbl th:nth-child(1)").truncate({
        width: myWidth ,
        after: "&hellip;",
        center: false,
        addtitle: true
}); ';

There is nothing wrong with the code you posted, so the issue is somewhere else. — simshaun

Perhaps the plugin expects a string and in the second snippet you're supplying it a number. — Andrew Whitaker

@Andrew Whitaker If I replace myWidth with "150" it works fine... It does not produce any errors, but the browsers keeps on spinning like it's waiting for something. It goes away as soon as I hard-code a numeric value. Weird, hah? — santa

Perhaps the plugin is expecting a string literal.

serverside:

echo '

    $(".myTbl th:nth-child(1)").truncate({
        width: "150" ,
        after: "&hellip;",
        center: false,
        addtitle: true
    }); 
';

js side:

echo '

    var myWidth = "150";

    $(".myTbl th:nth-child(1)").truncate({
        width: myWidth ,
        after: "&hellip;",
        center: false,
        addtitle: true
    }); 
';

That was my thought too. You could also just quote your value when setting it to myWidth. var myWidth = "150";

@idrumgood I think your solution is better. @mrtsherman Your code will cause a parse error in PHP unless I'm reading incorrectly. The width line should read width: myWidth.toString(),.
