使用列标题定位并搜索

公用js

common.js

function input_text_addSearchPre(modeId, targetId, selectId, valueId) {
    $("#" + valueId).attr("onkeydown", "if(event.keyCode==13){event.keyCode=0;event.returnValue=false;input_text_addSearchPost(‘" + modeId + "‘,‘" + targetId + "‘,‘" + selectId + "‘,‘" + valueId + "‘);}")
}
function input_text_addSearchPost(modeId, targetId, selectId, valueId) {
    var model = $("#" + modeId + " option:selected").val();
    var colPo = $("#" + selectId + " option:selected").val();
    var value = $("#" + valueId).val();
    var tds = $("#" + targetId + " tr").find("td:eq(" + colPo + ")");
    $.each(tds, function() {
        if (model == 0) {
            if ($(this).text().indexOf(value) >= 0) {
                $(this).parent("tr").show();
            } else {
                $(this).parent("tr").hide();
            }
        } else if (model == 1) {
            if ($(this).text().indexOf(value) < 0) {
                $(this).parent("tr").hide();
            }

Ajax异步请求

返回普通String

            $.ajax({
                url : "/ChargingSystem/entrance/register.do",
                type : "POST",
                data : form_loginORregister,
                async : true,
                cache : false,
                contentType : false,
                processData : false,
                success : function(returndata) {
