jquery - Get parameter and value appended to the extension of .js file -


i'm working on site has js file included this:

<script type="text/javascript" src="script.js?param=value"></script>

is there way can - inside script.js - param , value?

since script runs synchronously html parser, can last script element , read src:

var scripts = document.queryselectorall("script"); var script = scripts[scripts.length - 1]; console.log(script.src); // "script.js?param=value"

then use string parsing grab what's after ?, break name/value pairs, etc.

or if use async or defer on script element , may not last one, 1 src contains script.js:

var script = document.queryselector("script[src*=script.js]"); console.log(script.src); // "script.js?param=value"

this bit less reliable, since scripts can renamed. use queryselectorall("script") , find 1 parameters of sort expect.

for avoidance of doubt: don't recommend it. prefer pass options initialization call, or requiring object defined before script added (like google does), etc. can done.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
