See :hover state in Chrome Developer Tools

由 自闭症网瘾萝莉.ら 提交于 2019-11-26 03:28:51
问题 I want to see the :hover style for an anchor I\'m hovering on in Chrome. In Firebug, there\'s a style dropdown that allows me to select different states for an element. I can\'t seem to find anything similar in Chrome. Am I missing something? 回答1: Now you can see both the psuedo-class rules and force them on elements. To see the rules like :hover in the Styles pane click the small :hov text in the top right. To force an element into :hover state, right click it. Additional tips on the

问题 I was working with the developer tools of google chrome on a page without jQuery (or any other library that uses the $ sign as a shortcut). When I inspected $ by the console (by just typing it in and hitting enter), i got this: $ function () { [native code] } So, chrome has some native function that can be referenced by $ . Only chrome seems to have this one and i cannot access it via window[\'$\'] nor via document[\'$\'] or this[\'$\'] . I was not able to find out what this function is. Do

Google Chrome console.log() inconsistency with objects and arrays

由 不打扰是莪最后的温柔 提交于 2019-11-26 03:22:08
问题 I was helping a colleague debug some code today and I noticed a strange behavior with console.log() in Google Chrome: It appears that if you: Create a nested array (e.g., [[345,\"test\"]]) Log the array to the console with console.log() . Modify one of the inner array values, then console.log() will output the later value -- not the values of the array at the time the console.log() was executed. JavaScript : var test = [[2345235345,\"test\"]] console.log(test); test[0][0] = 1111111; //

What does ==$0 (double equals dollar zero) mean in Chrome Developer Tools?

由 两盒软妹~` 提交于 2019-11-26 03:16:04
In Google Chrome's developer tools, when I select an element, I see ==$0 next to the selected element. What does that mean? deadlock It's the last selected DOM node index. Chrome assigns an index to each DOM node you select. So $0 will always point to the last node you selected, while $1 will point to the node you selected before that. Think of it like a stack of most recently selected nodes. As an example, consider the following <div id="sunday"></div> <div id="monday"></div> <div id="tuesday"></div> Now you opened the devtools console and selected #sunday , #monday and #tuesday in the

What&#39;s the difference between “Normal Reload”, “Hard Reload”, and “Empty Cache and Hard Reload” in Chrome?

由 戏子无情 提交于 2019-11-26 02:16:36
问题 I recently discovered this new feature in Chrome: I can figure out the difference between option 1 and option 3, and that option 2 is probably something in between, but I can\'t find any more precise information anywhere. Anybody know the precise behavior of each of the 3 options? 回答1: Normal reload The same thing as pressing F5 .
