问题描述
每当我在jshint.com中
In jshint.com whenever I do
var this_hold = this;
我得到一个错误.
我违反了严格的错误.
应用程序是如此,我需要使用它(从事件处理程序中传入),或者我需要使用document.getElementById()
The application is such that I need to work with either this ( passed in from an event handler) or I need to pull the element myself using document.getElementById()
这是该功能发挥最大作用的方式...否则,对于每种情况,我必须编写两次.
It's just how this function works best...otherwise I have to write it twice once for each case.
我希望错误消失.我不想将其关闭.我希望jshint.com 100%满意.
I want the error gone..I don't want to turn it off. I want jshint.com 100% happy.
这是有问题的函数,其中注释了违规行为
Here is the function in question with the violation commented
/**
*vFlipBP - eliminate select_element in favor of 'this'
*/
function vFlipBP( element_or_string ) {
var previous_page_element,
previous_tag_element,
current_page_element,
select_element;
console.log( 'element_or_string ' + element_or_string );
if( typeof ( element_or_string ) === 'string' ) {
select_element = document.getElementById( element_or_string );
} else {
select_element = this; // violation of strict here
}
if( vFlipBP.previous_id === undefined ) {
var probe_id = select_element.parentElement.firstChild.id;
if ( ( probe_id === select_element.id ) && ( select_element.parentElement.firstChild.nextSibling ) ) {
probe_id = select_element.parentElement.firstChild.nextSibling.id;
vFlipBP.previous_id = probe_id;
} else {
vFlipBP.previous_id = select_element.id;
}
}
current_page_element = document.getElementById( select_element.id + '_page' );
current_page_element.style.display = '';
select_element.style.background = "#eeeeee";
if( vFlipBP.previous_id !== select_element.id ) {
previous_page_element = document.getElementById( vFlipBP.previous_id + '_page' );
previous_tag_element = document.getElementById( vFlipBP.previous_id );
if( ( ( previous_page_element !== current_page_element ) ) && ( previous_page_element !== null ) ) {
previous_page_element.style.display = 'none';
previous_tag_element.style.background = "#ffffff";
}
}
vFlipBP.previous_id = select_element.id;
}
推荐答案
您可以使用选项validthis
关闭该警告.不幸的是,您不能仅通过进行静态分析就检测到所有严格的模式违例,因此JSHint会做出猜测-有时是错误的.
You can use an option validthis
to turn off that warning. Unfortunately, you can't detect all strict mode violations just by doing static analysis so JSHint makes a guess—and sometimes it is wrong.
