userscripts - Obtain and check the value of an input text with javascript -

i new javascript , need script obtain value of input text , check value if equal 0 (zero). if need alert message notifying me text input 0. thanks. <input id="txtval" type="text" name="txtval" value="0" maxlength="10"> the short answer: if(txval.value==0) alert('please enter number.'); is not best answer: var v=document.getelementbyid('txtval'); v=parseint(v,10); if(v<=0) alert('please enter positive integer.'); of course not best answer either fix couple of common mistakes. although can refer element using id variable name not recomended. the value property of input (ie txtval.value ) string (even if contains digits) if try compare number may unexpected results. in case comparing 0 problems less if ever change code compare number run problems, best make actual number before it. if want allow decimals use parsefloat instead.

python - PyDev tab alignment in inline comments -

i'm sure there easy fix this, i've scoured preferences , haven't been able find option appropriate sounding name. here's simple example, top line isn't in code, there illustrate every 4th character position: # # # # # # # # = 2 # 2 b = "ab" # else foo between "something" , "two" hit <tab> twice, between "something else" , "foo" hit <tab> twice. my expectation using tab inside comment insert necessary spaces next tabstop (the way tab outside of comment works) instead, pressing tab inserts 4 spaces, regardless of column you're in. this doesn't happen in eclipse inside java project, leaves me believe it's pydev thing. just clear, expected hitting tab twice on first line , once in second produce: # # # # # # # # = 2 # 2 b = "ab" # else foo thanks in advance simple fix. p.s. hesitant tagging
