Vue current page push current page is invalid

When the push page jumps to the current page in the current page, but the parameters of push are different, you can only use string concatenation, parames and query will not work. I don't know why.

For example, the url of the current page is

/ invest/myinvest?page=1&day=0-30`

But you want to change the parameters when you click, so

This.$router.push ({path:'/invest/myinvest?',query: {page:1,day:'0-30'}})

However, there is no use for eggs.

Only:

This.$router.push ("/ invest/myinvest?page=" + currentPage+ "& day=" day); vue push error TypeError: Cannot read property 'push' of undefinedaxios.post (' / processing/', {}). Then (function (response) {console.log (response.data); if (response.data = = 'no_processing') {alert ("article analysis failed!") ; return;} else if (response.data=='empty_processing') {alert ("the article data is empty and cannot be analyzed!") Return;} response.data.forEach (function (element) {this.processing_tableData.push (element); / / "push" error console.log (element);}); console.log ("ok_processing")}) .catch (function (error) {console.log (error);})

Error report:

TypeError: Cannot read property 'push' of undefined

Solution method

Define a value externally to refer to the Vue instance

Var self = this; / / external definition axios.post ('/ processing/', {}). Then (function (response) {console.log (response.data); if (response.data = = 'no_processing') {alert ("article analysis failed!") ; return;} else if (response.data=='empty_processing') {alert ("the article data is empty and cannot be analyzed!") Return;} response.data.forEach (function (element) {self.processing_tableData.push (element); / / put "this" = "self" console.log (element); console.log ("ok_processing")}) .catch (function (error) {console.log (error)) }) this is the end of the content about "how to solve the invalid push current page in vue".
