WordPress主页加载弹出对话框SyntaxError：意外令牌：[关闭]

Question

I could not find anything online that matches my issue. When I load my homepage by typing it into the address bar, it loads fine. When I navigate to the homepage from another page on the site (by clicking the homepage link or the browser's back button), however, the following dialog box pops up.

"SyntaxError: Unexpected token :"

When I click OK, the dialog box disappears and the homepage loads as usual. I want to know the source of this dialog box popup and get rid of it. Any ideas or advice for troubleshooting is appreciated.

I am using WordPress 4.0, Jquery 1.11.1, and Salient theme. The issue is reproducible on Chrome and Safari browsers. Again, typing the homepage url into the address bar and pressing enter does not cause the dialog box to pop up. Navigating to a totally different site and pressing Back also does not cause the popup.

Thank you!

Answer 1

Your message comes from /wp-content/themes/salient/js/ajaxify.js

function _addtext(t) {
    try {
        $.globalEval(t);
    } catch (e) {
        alert(e);
    }
}

The string value of t is

{ "@context": "http://schema.org", "@type": "WebSite", "url": "http://128.199.247.11/", "potentialAction": { "@type": "SearchAction", "target": "http://128.199.247.11/?s={search_term}", "query-input": "required name=search_term" } }

Reproducing the result:

var t = '{ "@context": "http://schema.org", "@type": "WebSite", "url": "http://128.199.247.11/", "potentialAction": { "@type": "SearchAction", "target": "http://128.199.247.11/?s={search_term}", "query-input": "required name=search_term" } }';

try {
   $.globalEval(t);
} catch (e) {
   alert(e);
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js">
</script>

It happens because this string is equivalent of the

<script>
{"@context": "...", and so on }
</script>

and js does not know what to do with it while trying to eval the code.
