I’m using jquery and I have a question.
=ga.getText=function(a){var b,c="",d=0,f=a.nodeType;if(f){if(1===f||9===f||11===f){if("string"==typeof a.textContent)
return a.textContent;for(a=a.firstChild;a;a=a.nextSibling)c+=e(a)}else if(3===f||4===f)return a.nodeValue}
else while(b=a[d++])c+=e(b);return c},
d=*ga.selectors={cacheLength:50,*createPseudo:ia,match:X,attrHandle:{},find:{},relative:{">":{dir:"parentNode",first:!0}," ":{dir:"parentNode"},"+":{dir:"previousSibling",first:!0},"~":{dir:"previousSibling"}}
What does the selectors = {cacheLength: mean in jquery.min.js?
and also is it possible to change the value of cacheLength?
