如何在$ .post jQuery中等待响应 [英] How to wait for response in $.post jQuery

问题描述

PHP以1-2秒的延迟返回值jQuery.post不等待响应.

PHP returns value with 1-2 second delay jQuery.post doesn't wait for response.

您如何看待，是否有可能解决该问题并等待响应?

How do you think, is it possible to fix that problem and wait for response?

    $.post( sSource, aoData, function (data) {    
        oCache.lastJson = jQuery.extend(true, {}, data);
        if ( oCache.iCacheLower != oCache.iDisplayStart )
        {
            data.aaData.splice( 0, oCache.iDisplayStart-oCache.iCacheLower );
        }
        data.aaData.splice( oCache.iDisplayLength, data.aaData.length );
         abc(oCache);
        fnCallback(data); 
    },"json" );

注意与get相同的功能效果很好

Note the same function with get works well

    $.getJSON( sSource, aoData, function (json) { 
        /* Callback processing */
        oCache.lastJson = jQuery.extend(true, {}, json);

        if ( oCache.iCacheLower != oCache.iDisplayStart )
        {
            json.aaData.splice( 0, oCache.iDisplayStart-oCache.iCacheLower );
        }
        json.aaData.splice( oCache.iDisplayLength, json.aaData.length );

        fnCallback(json)
    } );
