Solve the problem of garbled gbk files on the JS request server _ javascript skills

This article introduces the garbled problem of the gbk file on the js request server. to solve this problem, you need to set xhr. overrideMimeType (& quot; textcsv; charsetgb2312 & quot, if you need a friend to learn about it, the JS file in gb2312 encoding format is garbled. the ajax network request uses XMLHttpRequest internally. Therefore, you need to set the encoding format before the request, however, xhr is configured. setRequestHeader ("accept", "text/csv; charset = gb2312, */*"); no effect. only xhr is set. overrideMimeType ("text/csv; charset = gb2312"); is correct, the code is as follows:

$. Ajax ({type: "get", url: "http://7xnhdv.com1.z0.glb.clouddn.com/test1.csv", beforeSend: function (xhr) {// beforeSend defines the global variable // xhr. setRequestHeader ("accept", "text/csv; charset = gb2312, */*"); xhr. overrideMimeType ("text/csv; charset = gb2312") ;}, success: function (xmlDoc, textStatus, xhr) {if (xhr. status = 200) {$ ('# view0 '). text (xmlDoc );}}});

OverrideMimeType overwrites the header sent to the server and forces text/csv; charset = gb2312 as the mime-type.
