javascript - How can I avoid flickering when image is changed for another with MouseEvent? -

-

i have clickable image (logo) want defined in html (not css) since it's logo sits in menu, should scaled text , semantic part of content.

i want change on hover so:

<img src="logo.svg"     onmouseover="this.src='logo_hover.svg'"     onmouseout="this.src='logo.svg'">

the problem menu , logo flickers when hover image. doesn't happen seems have takes blink new image scaled right. have width: 100% on logo , width: 5em set on div holds it.

how can avoid flickering? should set both width , height on image, if how find out height image should have? or there other way avoid browser being "surprised" when new image loaded?

what i've triend far:

i've tried preload image javascript, , <link rel='prefetch'> tag, flickering still happens.

based on looks you're trying do, advise against approach can manipulate properties of svg using css hover state.

what changing on logo - if may ask?

if case of colours etc use approach of using inline svg code directly html , using css apply colours etc. enables edit css properties hover state. problem using svgs via img tag can't edit properties — sure aware of.

for istance - svg logo:

css hover color change:

#my-logo{   fill: orange; }  #my-logo:hover{   fill: red; }

you have far more flexibility if want edit / manipulate svg properties method can avoid doing on convoluted javascript magician shazaam.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
